First of all, thanks a lot providing such a reliable and excellent CI/CD Tool with Jenkins!

Second, I assume this may not necessarily be a bug in the credentials plugin itself, but some otherwise triggered weird UI glitch.

If I add a new credential in the (global) credentials store (https://jenkins.domain.my/manage/credentials/store/system/domain/_/ everything works fine, I press '+ Add Credentials' and I get presented with the dropdown and the details:

BUT once I create a new credential inside of a custom domain: eg: https://jenkins.domain.my/manage/credentials/store/system/domain/test.example.com/newCredentials the details are missing and I can't set a custom id:

The problem seem only to occur on Firefox, I see the page normally with Chromium.

Additional info: it seems NOT to be an issue when the domain is only called 'test', but it appears with 'test.example.com'.
