Material not visible because it was saved without engine version/...imported, ...but it was never saved as an export.

Twinmotion 2021.1.4 to Unreal v4.27.2 (v4.26.2) and packing platform android (ASTC)
installed datasmith twinmotion importer plugin
installed twinmotion content for UE plugin

I’ve never seen this problem on a PC or in the mobile previewer on the PC. I’m only seeing it when I deploy the app to an actual Android device

Has anyone experienced anything like this? I have no idea where to look or what to try to resolve this, so any help would be greatly appreciated!
