Floating character

Hello! I’ve spent several days now working on a large scale open world map. I keep running into an issue where parts of my map make my character float above the terrain by a few feet. Its a new level height map build into the 3rd person editor. I can obviously go lower in other areas of the map but not in these few areas. I’ve turned on the collision mesh and it should be on the terrain level but I’m still floating. In one or two spots there’s a discernable edge (still invisible) that I can jump up on or fall off of. Never run into this and have no idea how to fix it. Any ideas? Thanks

Update… Corrupted map file
