Product Inquiry for WooCommerce FORM

I’m using

Product Inquiry for WooCommerce

It works correctly except when it opens the pop up with the form, it does not let me use the mouse cursor under any circumstances to use the inputs of the form.

I don’t understand that it is overriding the option because I can only use the tabbed.

Can anyone help me with this inconvenience?
You can verify it with the “consultar” button
