Unable to add github credentials to existing blcok

[sr33j]

Bug summary

I can't add my github credentials block to my github repository block. Every time I try to, it just says None in the github repository block.

It might be a bug with the UI?

Here is a slack message with the screen recording of the issue: https://prefect-community.slack.com/archives/CL09KU1K7/p1763760008474899

Using existing credentials does not work in the UI with bitbucket repository blocks either, but it's not too hard to do from python code if you're stuck.
