Hi mserena -
The Red Matte material that your BP applies at runtime, can you go into that material and see if in the Material Attributes Usage section, if Used with Skeletal Mesh is checked true, if not please check it true, save your material and then run your BP test again.
If you are still getting an issue, I might need to see the BP that is generating the test from your above picture.
Thank You -
Eric Ketchum
