5.7 Motionmatching, character slides in idle pose

I would like to create a basic motionmatching setup for an NPC.

So far I got working:

The npc follows the player when the game starts.

The motionmatching part appears to not work entirely. It basically plays whatever is the base output pose (in this case idle) while sliding towards the player.

If I remove the idle pose from the pose search database it plays whatever is the topmost output pose. I am not sure where the error is:

I have the pose search and trajectory plugins loaded. I think something is wrong in the way the trajectory is used.

Here is a screenshot of the trajectory debug lines when the character approaches me. When I circle it, the front area of the prediction turns into a blue star (lines fanning out in a 180 degree angle).
