*Steps to reproduce:*
# Navigate to [Tanks! Tutorial | Tutorial Projects | Unity Asset Store|https://assetstore.unity.com/packages/essentials/tutorial-projects/tanks-tutorial-46209] and click on 'Add to my assets'
# Open a Unity project
# Open Package Manager via Window > Package Manager
# Navigate to the My Assets tab
# Find the Tanks Tutorial asset
# Select the asset and download it
# When the download is complete, click Import to project
# On the warning pop-up, click 'Import'
# On the next warning pop-up, you can choose to either skip or Install/Upgrade (Skip is faster)
# Click 'None' to untick all assets

*Actual results:* The 'None' button is still active and the user can still Import (even though they have not selected anything). There are disabled assets (e.g. SampleScene.unity) and these count as being selected:

*Expected results:* The 'None' button is greyed out as all assets are unselected. The user is also not able to click 'Import' as nothing is selected. There is either no disabled assets or they are not counted as being selected.
