Form Select, titleAttribute does not appear

I have the following tables: zero_ones(id, data) tests(id, zero_one_id [nullable and unique], data) I created a resource for "Test" and in the select input, I specified to only bring zero_ones that are not yet related to a test. When searching and relating it for the first time, it works, but when I go to edit an already related one, the titleAttribute does not appear, only the id does. I assume this is because it's not fetching the current or the same one. How can I retrieve the title of the currently selected one, or how should I handle this? Thank you in advance.
