Cannot add textures from migrated model

Summary

I am trying to change a migrated product with only a 2D media view to a 3D media view.
The problem is that I can upload the OBJ but when I try to add the materials I am unable too. I cannot drag or upload the materials.

This is only happening to two of the migrated models.

I would like to delete the listing and start a fresh but I can’t as the delete listing is greyed out.

What type of bug are you experiencing?
