UI Toolkit PSB Import Sprite Atlas

So I'm trying to display various sprites from my PBS import into the UI Builder, but when I select a sprite from the import, it defaults to just this arm sprite, and then when saved resets the background image to "Texture" instead of sprite, and keeps the arm sprite.

The result after selection

After saving and reloading

No matter what sprite I select from the object picker it...
