Roblox Studio Insert Model Error

Anyone know why every time I insert a model from the Toolbox or from what I get, the results are always weird. Like the union is getting bigger, etc. Meanwhile, when I check the viewport in the browser, the model looks correct, but when I upload it, it gets messed up.

Happened since 3 days. Anyone know why every time I insert a model from the Toolbox or from what I get, the results are always weird. Like the union is getting bigger, etc. Meanwhile, when I check the viewport in the browser, the model looks correct, but when I upload it, it gets messed up. But when I told my friend to insert the same model, this didn’t happen. Anyone know why?

Look at this example,

This is from the browser and when my friend insert it looks like this.
But when I insert

Example 2:
From my friend

From me

I already try uninstall and install again but still the same.

Yes that could be a bug reinstall studio or restart with model. Or try to see it in game

I delete regedit and fix the error but when i close the studio and open again, error again.

Reinstall doesn’t fix it, idk why. It’s been three days with this bugs.

How it appear in roblox application?

is this happen right after insert
or after, you resize and edit?

Right after insert, that’s why I feel weird. char…
