UMAP not Available in Engine, but it is in the Project

Hey everyone,

I have a project from the marketplace and I’m trying to migrate everything over to my own project. Most of the assets migrate correctly, but there is a .umap that doesn’t. It appears in the file explorer, so it is there, but I can’t access it in the engine. The build data is there, but not the level itself. It isn’t in the content drawer and it doesn’t appear in any dropdown menus like the ones in Maps and Modes. Most forums seem to agree that this happens when the two projects are different versions of the engine, but both of these are the same (5.1). Does anyone know how to get my level?

Thanks in advance.
