Would you mind elaborating a bit more about the issue you are experiencing? What is the workflow/steps you are doing? A small video recording of the same would be very helpful.
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 22.3.20281 (Mac) or 22.3.20282 (Win) installed. Go to Help > Check for updates and reboot the computer once.
Also try to repair the installation from the help menu (Win Only) and see if that works.
