Solved Problem with a Sticky form on Divi, some fields are behind an invisible form or something

Hi! I’m trying to use Gravity Forms in a column that keeps sticky while users scroll down.
When the form is NOT sticky everything seems to work fine.

But once the column and form become sticky, there is something invisible blocking the form.

This is the first time something like this happen to me.

I don’t know if this s a Divi problem with their sticky feature, or if there is something that can be done from Gravity forms side.

I’m posting this in both forums and also trying to talk to Elegant Themes.

This is the link to the site with the forms acting weird:

If you use the Web Inspector you can see that something invisible appears just in front of the form when the sticky feature begins to work. If you delete all that row from the web inspector the forms is usable again.

So I’m trying to figure out how to prevent that invisible row to appear.

Thanks for any help.
