Conflict between 2 search forms on one search results page

I have a search results page with 2 search forms: Form A is the in the sidebar and is autosubmit, Form B is a duplicate of Form A. It is in a mobile overlay widget (https://wordpress.org/plugins/genesis-widget-overlay/) only seen when the overlay trigger button appears below a certain media query.

So the idea is, on desktop the user can use Form A in the sidebar. When the site moves down in resolution or is in mobile, the sidebar is hidden via CSS, the overlay trigger button appears and now the user can access Form B as an overlay widget.

This setup works fine if both forms are autosubmit. However, if I try to set Form B to require the use of a submit button it continues to use autosubmit. And if I set Form A to require the use of a submit button, Form B just stops working.

At that point, if I remove Form A from the sidebar, Form B in the overlay will now work, requiring use of a submit button.

There seems to be a conflict going on between forms. Any idea how to fix this? I can provide a link or record a screencast of the behavior.

Thanks!
