In Field Management, I have hidden fields that are still showing up in the user interface.
Here's an example of hidden fields:
The field is mapped to SFDC. I attempted to block field updates as well and it is not being used by any assets.
But the hidden fields are still showing up in the drop down selection in Marketing Activities. (I did not name these. They came in from SFDC.) I don't want others on my team to be able to select the old/outdated field especially when they are so closely named.
