User details change not seen in assignee autocomplete choice

[Alexey P]

I had a fake user with email list to notify my team.

Now the convention for group names and their emails has changed in my company.

I have updated fake user with new friendly name and new email and created new similar fake user.

My changes can be seen in Administartion but not seen when creating new issue.

New user I just created work fine though.

Is there a way to propagate the change?

After trying all sorts of things I changed project roles for the user and it worked. Looks like a bug.
