User DYdave Unable to assign contribution credits

Great job reworking the interfaces for managing contribution credits, it's a very welcome change! 🙂

Problem/Motivation

As I was updating tickets yesterday for the Admin Toolbar module, I was able to assign contribution credits on two tickets and then it stopped: Unable to assign any contribution credits in the module at all.

See for example:
#3552168: Standardize display order of extra links menu items →
with its contribution credits:
https://new.drupal.org/contribution-record/11427999

Now, if I try changing the credits on this page, the following message will be displayed:

You need to be a maintainer of the module to make changes.

When just a few hours ago I was able to properly see the Save and Syn from source buttons....
I tried to logout and login again but without any effect ...

This is now the issue for which I am really unable to assign credits:
https://new.drupal.org/contribution-record/11427714

I have attached a screenshot of the page on which the error currently occurs:

But I have tested with other tickets of the module and it seems to be the same.
 

Any help, advice or suggestions on how we would be able to still assign contribution records to contributors would be greatly appreciated.
Feel free to let me know at any time if you have any questions or would need more information, I would be glad to reply as soon as possible.
Thanks in advance!
