This happens when you are a Managed User and use the search bar along the top. It gives you an entry lists the server-name and a (+X) to indicate that the search result is in multiple libraries. Clicking on the base image takes you to a -FILTER- for the actor in the first library it found (arbitrarily chose), not the user’s full/partial profile in “Discovery”:
As an admin, the exact same search yields the actor’s “Discovery” link instead:
This came up in another topic recently. No notice from Plex about whether this was intended or not. I believe it has to do with “Discovery” being disabled for Managed Users, which causes search results to bring up a filter instead of the profile.
What is most frustrating about this is that you CAN get to an actor’s profile on a Managed User account, you need to select their profile pic in any movie they are in. This isn’t the FULL profile that lists all movies not in your server, but with discovery disabled for Managed Users, you wouldn’t be able to do that anyway.
For the OP: Click on 21 Jump Street, then click on his portrait in the cast list to get his full filmography.
