Player Marker not working as expected when marking a player who has the flag in a CTF game mode.

I am creating a Capture the Flag game and I want the Player Marker Device to mark the player who picks up the flag so others can see who has the flag. I have it set to enable, disable, everything correctly, but when I or another player picks up the flag, it marks the whole team instead of just the player who has the flag. So it looks like everyone has the flag instead. Is this a bug?

Also, a few weeks ago there was an option to have a beacon so a beam of light would be visible on the player who has the flag. This was working perfectly, but it seems that Epic removed that functionality from the Player Marker Device. Why???
