Hi Damien,
For this particular table do you have any script running or any custom html on the page? Does it only ever happen in the mobile version like your screenshot above or does it also happen in the desktop version? Is it confined to a single table or is this happening on multiple tables? Within that table is it only happening on one form or all the forms?
I agree with Matt if you don't currently have a support case in with Quick Base Care I would suggest creating one. That way a Care Rep can get an invitation into your application to try to isolate what is causing this issue. They can do some testing with the fields and forms to see if it might be a script or html that isn't loading correctly.
