Test Field Modified Unapply Logic

Description

According to Emily in the testing document, "When I changed and deleted a doc type pattern on the delta URLs, the URLs disappeared from the delta URLs tab, even though they were there from the start".

We need to improve the test coverage for unapply logic and uncover any unexpected behavior.
