UE4.26 Buoyancy not working?

Hey All, I’m running into an issue using my custom buoyancy BP… Ann even using the default buoyancy cube BP. My custom water mesh will not allow objects to float on its surface. Every time I place a buoyant object above my water and press simulate, the static mesh actor will just fall through the water. I thought it was the custom water mesh so I created a landscape, added a lake to it, and the buoyant mesh does the same thing. Does anyone know what the issue could be? Below is a video showing my problem. Thanks!
