Roblox Studio exporting .OBj model's incorrectly as of a recent update

Update: Found a setting ‘Merge materials on export’, and thought that would be the fix. It wasn’t, having this issue with it toggled on or off, seems like a recent update broke this setting? Any update would be great, this makes creating large and detailed maps almost impossible unless you’re willing to let your part count reach the hundred-thousands.

Any news, or even work around would be amazing.
