Hi McKenzieClaydon
Hope you are doing well and sorry for the trouble. As described you are unable to delete the renamed text field as it becomes a random text field.
I have tried to reproduce the issue on my end on Windows 10 machine using Adobe Acrobat DC with latest version and its working fine.
Would you mind sharing the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version 21.01.20155 installed. Go to Help > Check for Updates and reboot the computer once.
Is this a behavior with a particular PDF file or with all the PDFs ? Please try with a different PDF form and check
You may also try to reset the Acrobat preferences to default as described in the help page - https://community.adobe.com/t5/acrobat/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082 and see if that works
Also please try to create a new test user profile with full admin rights or enable the root account in Mac and try using the application there and check.
Regards
Amal
