I'm currently setting up an automation rule which includes adding six watchers. For some reason one of the users is not being included as a watcher when the rule is triggered. When I investigated the rule, I noticed that all the users where with their Name and linked(underlined), while this user stayed with his username and not linked.
I also created other rules which I assigned this user as an assignee, and such rules worked perfectly fine.
Same permissions are applied to a group of users which none have this issue except for this user. I am able to add the user manually. The issue is only when trying to use the Automation tool which the user profile doesn't seem to link with the user profile.
