Variations are not showing, PHP Deprecated: options.php argument

I am testing the plugin on a Hebrew site.
On admin panel, whenevr I save the options on the setting tab.
I get the following in my debug.log (showing only 2 lines):

[26-May-2020 17:05:55 UTC] PHP Deprecated:  options.php נקרא באמצעות ארגומנט שכבר <strong>לא קיים</strong> מגרסה 2.7.0! ההגדרה <code>_woovr_show_description</code> איננה קיימת. הגדרות לא רשומות הוצאו משימוש. ראו https://developer.wordpress.org/plugins/settings/settings-api/ in /home/lagunamulli/public_html/wp-includes/functions.php on line 4997
[26-May-2020 17:05:55 UTC] PHP Deprecated:  options.php נקרא באמצעות ארגומנט שכבר <strong>לא קיים</strong> מגרסה 2.7.0! ההגדרה <code>_woovr_show_availability</code> איננה קיימת. הגדרות לא רשומות הוצאו משימוש. ראו https://developer.wordpress.org/plugins/settings/settings-api/ in /home/lagunamulli/public_html/wp-includes/functions.php on line 4997

Translation: options.php is called with an argumen that does not exists since 2.7.0.
Definitions not listed are not in use (not sure about translation of last 3 words). see https://developer.wordpress.org/plugins/settings/settings-api/ in <my-path>/wp-includes/functions.php line 4997
I have coppied only 2 lines from debug.log, for readability. The complete list is for:

<code>_woovr_active</code>
<code>_woovr_hide_unpurchasable</code>
<code>_woovr_selector</code>
<code>_woovr_variation_name</code>
<code>_woovr_show_clear</code>
<code>_woovr_show_image</code>
<code>_woovr_show_price</code>
<code>_woovr_show_description</code>
<code>_woovr_show_availability</code>

Hope that helps.

WPC plugin that I am using:

<?php
/**

 * Requires at least: 4.0
 * Tested up to: 5.4.1
 * WC requires at least: 3.0
 * WC tested up to: 4.1.0
 */

I guess issue is related to the following lines:
(action=options.php is on line 137 in the code)

   <div class="wpclever_settings_page_content">
    <?php if ( $active_tab === 'settings' ) {
	$woovr_active             = get_option( '_woovr_active', 'yes' );
	$woovr_hide_unpurchasable = get_option( '_woovr_hide_unpurchasable', 'no' );
	$woovr_selector           = get_option( '_woovr_selector', 'default' );
	$woovr_variation_name     = get_option( '_woovr_variation_name', 'default' );
	$woovr_show_clear         = get_option( '_woovr_show_clear', 'yes' );
	$woovr_show_image         = get_option( '_woovr_show_image', 'yes' );
	$woovr_show_price         = get_option( '_woovr_show_price', 'yes' );
	$woovr_show_availability  = get_option( '_woovr_show_availability', 'yes' );
	$woovr_show_description   = get_option( '_woovr_show_description', 'yes' );
    ?>
     <form method="post" action="options.php">
	<?php wp_nonce_field( 'update-options' ) ?>
             <table class="form-table">

According to the WordPress codex, I suspect it should be something like:

<form method="POST" action="options.php">
<?php settings_fields( 'my-page' );	//pass slug name of page, also referred
                                        //to in Settings API as option group name
do_settings_sections( 'my-page' ); 	//pass slug name of page
submit_button();
?>
</form>
