How to determine which template a custom field is used in

Whoops…sorry for the mistake; I have the exact situation as both of you; two Asana-created custom fields.

(One was scrolled off the list I was looking at of the library’s custom fields so I jumped to the wrong conclusion when I wrote my post before; sorry.)

I’m not sure why one of these shows it was created by me, but it’s the same situation as both of you, and neither can be deleted, only removed from projects or My Tasks.

Is this the solution (in thread @Andrea_Mayer linked to):

That requires 1) requesting Support to unblock the field, then 2) carrying out the steps yourself, it seems.

Thanks,

Larry
