Hi everyone,
We are having an issue with the custom avatars of all people added to the staff category. All other group member avatars are working fine and as intended.
For example, please check this video:

This is the live link to check the issue.
We also tried to switch to safe mode and disabled all custom plugins/themes etc to see if the issue persists. But yes, it’s still there.
We are running the latest version of Discourse (all upgrades are done to date).
Any idea what the issue could be? And how we can solve it? 
Thanks in advance!!
