Signature not functioning on WooCommerce Tab

I have read through the other topics that appear to be similar in nature, but cannot seem to apply the solution to this particular case.

I have products that will have a contact form 7 with signature applicable to one of the custom tabs (YIKES Custom Tabs plugin), so it is not on the default tab and is ‘hidden’ by default. When selecting the tab, the signature box is visible but cannot actually fill the form.

Product with ‘player waiver’ tab signature not working: http://guitard.ca/wp-test/product/test/

The form works by itself: http://guitard.ca/wp-test/account/
