Hi and welcome back!
First of all, thank you for doing this as it’s usually very helpful in identifying the source of conflict:
To be sure it wasn’t any customization causing this we removed everything from our child theme .css and functions.php
With that said, would you mind reviewing our Testing for conflicts guide to see if we can rule out the chance of a theme and/or plugin conflict? Once you’ve done that, reply back with your findings and we’ll continue investigating.
I did a quick check of our logged bug reports and don’t see anything resembling what you’ve described and what I’m seeing in the screenshot provided. Thanks again and have a great rest of your day. Cheers!
