No more target lock in the seeker view?

Hey all, since the update I am not able to “lock on” to any target. I use the middle mouse button to stabalize the view and then “lock” the target. Now I have to manually follow the target until the eg Hellfire hits which makes it quite hard to hit it. I looked everything up in the settings, even made a new installation of the game … any help would be appreciated!

Its bugged atm. It should work as long as you keep your radar turned on.
