Problem changing form to another language.

Hello,

I use the TranslatePress plugin to translate the web from Czech to English.
This plugin (its free version) does not allow automatic translation (it is necessary to create it manually).
However, the form cannot be changed. If I display a form in the plugin editor, this will appear instead of the text.

<div class="wpforms-container wpforms-container-full" id="wpforms-97"><form id="wpforms-form-97" class="wpforms-validate wpforms-form wpforms-ajax-form" data-formid="97" method="post" enctype="multipart/form-data" action="/en/?trp-edit-translation=preview"><div class="wpforms-field-container"><div id="wpforms-97-field_0-container" class="wpforms-field wpforms-field-name" data-field-id="0"><label class="wpforms-field-label" for="wpforms-97-field_0">Jméno a Příjmení <span class="wpforms-required-label">*</span></label><div class="wpforms-field-row wpforms-field-medium"><div class="wpforms-field-row-block wpforms-first wpforms-one-half"><input type="text" id="wpforms-97-field_0" class="wpforms-field-name-first wpforms-field-required" name="wpforms[fields][0][first]" required><label for="wpforms-97-field_0" class="wpforms-field-sublabel after wpforms-sublabel-hide"><trp-gettext data-trpgettextoriginal=14>First</trp-gettext></label></div><div class="wpforms-field-row-block wpforms-one-half"><input type="text" id="wpforms-97-field_0-last" class="wpforms-field-name-last wpforms-field-required" name="wpforms[fields][0][last]" required><label for="wpforms-97-field_0-last" class="wpforms-field-sublabel after wpforms-sublabel-hide"><trp-gettext data-trpgettextoriginal=16>Last</trp-gettext></label></div></div></div><div id="wpforms-97-field_1-container" class="wpforms-field wpforms-field-email" data-field-id="1"><label class="wpforms-field-label" for="wpforms-97-field_1">Email <span class="wpforms-required-label">*</span></label><input type="email" id="wpforms-97-field_1" class="wpforms-field-medium wpforms-field-required" name="wpforms[fields][1]" required></div><div id="wpforms-97-field_5-container" class="wpforms-field wpforms-field-text" data-field-id="5"><label class="wpforms-field-label" for="wpforms-97-field_5">Telefon</label><input type="text" id="wpforms-97-field_5" class="wpforms-field-medium" name="wpforms[fields][5]" ></div><div id="wpforms-97-field_2-container" class="wpforms-field wpforms-field-textarea" data-field-id="2"><label class="wpforms-field-label" for="wpforms-97-field_2">Komentář <span class="wpforms-required-label">*</span></label><textarea id="wpforms-97-field_2" class="wpforms-field-small wpforms-field-required" name="wpforms[fields][2]" required></textarea></div></div><div class="wpforms-field wpforms-field-hp"><label for="wpforms-97-field-hp" class="wpforms-field-label">Comment</label><input type="text" name="wpforms[hp]" id="wpforms-97-field-hp" class="wpforms-field-medium"></div><div class="wpforms-submit-container" ><input type="hidden" name="wpforms[id]" value="97"><input type="hidden" name="wpforms[author]" value="1"><input type="hidden" name="wpforms[post_id]" value="5"><button type="submit" name="wpforms[submit]" class="wpforms-submit " id="wpforms-submit-97" value="wpforms-submit" aria-live="assertive" data-alt-text="Sending..." data-submit-text="Odeslat">Odeslat</button><img src="//www.varnsdorfskapradelna.cz/wp-content/plugins/a3-lazy-load/assets/images/lazy_placeholder.gif" data-lazy-type="image" data-src="https://www.varnsdorfskapradelna.cz/wp-content/plugins/wpforms-lite/assets/images/submit-spin.svg" class="lazy lazy-hidden wpforms-submit-spinner" style="display: none;"><noscript><img src="https://www.varnsdorfskapradelna.cz/wp-content/plugins/wpforms-lite/assets/images/submit-spin.svg" class="wpforms-submit-spinner" style="display: none;"></noscript></div></form></div> <!-- .wpforms-container -->

If I copy it and change the texts to English, it doesn’t affect.
In addition, there is no translation when editing again.

Please for advice.

Thank you
