Multiple Pop-Ups - Trying to get rid of one!

Site URL: https://www.vbccc.com/

After contacting the SquareSpace help desk, they recommended I ask in this forum. I have a Promotional Pop-up (see pic) that I created in the Marketing tab on SquareSpace. However, someone who previously managed our website somehow created, perhaps using Code Injection, another promotional pop-up that I can't "find" and delete. It's a pop-up to subscribe to our email list. Any suggestions?

I'm answering my own question! Hopefully this will help someone in the future. I went to PAGES, then hovered over the "Settings" gear, and selected "Advanced" from the Menu. Sure enough there was a code injection for MailChimp so I simply deleted it and now that additional pop-up is gone!
