Opening Saved Level

I am trying to load a level I previously made in Unreal and Unreal is not recognizing its own .umap extension. I can see the level I made in the folder but the Open Level window does not… Help? I am not sure how to fix this. Thanks!

Is it a part of some other project? If so, then you could migrate your level to your new project.

It is part of the same project. I also noted this happening on my school computers when I created a new project, created a level, closed it, and then opened it. When it opened I had not set the level I made as the default one to open and so I tried to load it and it would not come up.
