List of steps to reproduce (step by step, including full links if applicable):

• Open page for Z8021

What happens?:

• It is saying it is "not associated with its function" - "function: If (This object is not associated with its function.)"
• Also in the Tester Results section it says "No tester results found. Please add an implementation and a tester to see results."
• Additionally, on the function page (Z802) this test now fails. I don't know why - there's no explanation of the failure.

What should have happened instead?:

• A couple of weeks ago it *was* associated with its function, and on the function page you can see this tester listed so it really should be.
• Also a couple of weeks ago there was a way to run just this tester against the implementations of the associated function; now this has disappeared.

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc: I just ran git pull on everything, so up to date as of this morning (2021-12-20)
