Jitters on Static Mesh Pawn

Hi all! First time on here. I am very new to UE. Here’s my issue: I created a pawn Blueprint and used a Static Mesh. I have placed that in a WaterBodyLake, it floats via the Buoyancy component but there’s a lot of jitters on the mesh… so much so that it starts moving all by itself before input is even provided. I read on here somewhere that turning off gravity eliminates it, it does, but that then also eliminates the realistic bobbing of the static mesh cube in the water.

Please help! Much thanks in advance!
