By the way, on acrobat preferences>forms>highlight color turn off show border hover color for fields.
You did not post a screen shot. Does it look like this?
On a Mac in Acrobat DC, go to Preferences > Forms and uncheck Show Border hover color. Or change the colors. The red border indicates a required field. In older versions there was a bar across the top.
It will now look like this:
Second choice: leave it alone. The indicators serve a purpose.
Thank you for your help!
I checked the settings and it solved the problem.
Keep in mind, preferences (including form display) are your application settings, and does not control how others will view the form fields.
