Remove appearance from Document asset browser

Hello everyone

Is there any solution how to remove material asset from document file? 
We deleted material but it still shows in Asset Browser in Document Assets.

For example: I deleted "Default Mass Exterior Wall" from materials, but appearance still show in Asset Browser.

As I understand, Assets are parts of Materials.  Once unused material is deleted, you must also purge the remaining Asset.

Purge > Check None > Check those items you want to delete?
