Sorry, didn't realise someone had the same problem and didn;t see the post ebfore mine.
We apologize for the inconveniences this may have caused. This issue has been resolved already, I made a test with one of my forms and the uppercase text remains intact.
I would recommend you to remove the current Text field, re-add it, then enter your upper case text. If the issue still persists, try logging out of your Jotform account,clear your browser caches and cookies, clearing your form caches while logged in your account may also help, here is how: How to clear your form cache
