Steps to reproduce:
1. Create a Universal 2D project
2. Create Auto Tile Asset (Create > 2D > Tiles > Auto Tile)
3. Select newly created Auto Tile Asset and press “+” button in the Used Textures section in the Inspector
4. Select any texture
5. Observe texture preview
6. Remove newly added texture by pressing “-“ button

Actual results: Texture is removed but texture preview is still visible
Expected results: Texture and texture preview are removed

Reproducible with versions: 4.3.1 (6000.1.14f1), 5.0.1 (6000.2.0f1), 6.0.0 (6000.3.0a4)
Couldn’t reproduce with versions: 2.2.8 (2021.3.54f1), 3.1.3 (2022.3.65f1), 4.1.0 (6000.0.55f1) (No Auto Tile Asset)

Tested on (OS): Windows 11, macOS Sequoia 15.4 (M4)

Note: Clicking on another Asset and clicking on Auto Tile asset again removes the preview
