Bug in Pricing Table Pro

I’ve sent you few emails but without response.
There is a bug when you add icon shortcodes or html icons (eg <i class=”material-icons”>event</i>) in table fields, above “Tooltip or Info Text”, when you save first time works well, but then shortcode is cut by the middle or the html code directly disappear, when you save again all is broken, in your selling page you say that this field admit shortcodes , the only that are admitting at the moment are [y] and [n].
Send me a fix asap that resolves this issue.
Thanks
