Nav Mesh Seams?

I’m hoping someone can help me out with this. I’m setting up a modular building system that allows the user to place static meshes into the game and have an AI use a newly placed item to walk around the level. My particular issue is with stairs. When I place some stairs into my level the Nav Mesh rebuilds itself and looks like it should work but I notice a “seam” between some of the levels. Occasionally it’s just on the first instance of the placement and from there the AI will move just fine, but other times the AI hits the “seam” and stops walking. I’ve been playing around wth the settings and can’t pin point which one would fix the issue. This is what the “Seams” look like. Any help would be greatly appreciated!

Found the solution to my own problem. The Meshes I was using were too small for the Nav Mesh tile size. Even at the smallest size it was having issues. Luckily I wanted to test the mechanics before diving into mass asset creation, so I’ve just doubled the size of my meshes and everything is just peachy.
