After many attempts at different fixes, I was able to get all of my glass to cooperate by creating a Blueprint of the Mesh I made. As an important note to anyone that stumbles across this in the future, I originally made the mesh Plane using the Quick Place Actors menu under Shapes. I then applied a material to it and set my desired collision. Again this worked fine for many hours until it didn’t.
I went into Modeling Mode and just created a rectangle, I applied my glass material, and then created a Blueprint using the mesh which is a right-click menu option. After I replaced all my old static meshes with this new Blueprint version, everything worked exactly as it should.
This is NOT a resolution however. It’s a workaround for an issue that exists in the editor. The absolute location of an asset within your environment should never be in question. The coordinates are the coordinates.
