Floating AI falls down while moving, why?

The initial location of my AI is (100, 100, 400). And it’s floating in the sky. However, after I tell it to move to me, it falls down while moving to me. Why? I want it to float in the sky all the time. How can I make it?

after moving:

Im guessing your movement mode is walking? you could try using using flying as default land movement mode.
Or if you want to fake it make the capsule taller and place the mesh towards the top of it and it will appear to be floating at the height you want with the bottom of the capsule sitting on ground.

yes the movement mode is not floatingpawnmovement and the collison+ the setting enabled to objey gravity tells it to drop down
