HELP: MD obj files importing without uv map

So I made some new meshes today using marvelous designer after downloading an update that supposedly fixed some bugs. When i exported my garments as OBJ files and imported them into blender, parts of the garment were missing from the uv maps, but only for some files that I exported. I don't know why they suddenly began to export improperly. Anyone know how to resolve this issue?

I tried uninstalling and reinstalling the program and choose not to install the update when prompted, but the issue remains.
