Hello and welcome to the forums!
Sorry to hear about the widget display issue. I wish I was able to provide more support, but theme conflicts/customizations extend beyond the scope we’re able to provide :-/
With that said, the best I can offer is to visit your site and open “Inspect” by right-clicking on your mouse. Once you have that open, you can identify CSS classes and begin to make changes.
We’ve also got a great deal of users using the Divi theme, so there should be a decent amount of support searchable via our forums and the search engine of your preference.
Again, I apologize I can’t be of more assistance and best of luck with the customizations 🙂
