To reproduce:

1. Open the project, attached by user (StatSystemProject.zip)
2. In Project View, type t:BaseStatType in the search bar
3. Observe how many assets are found (found 3, but there are 10)

Expected: searching for assets by type shows all the assets of that type
Actual: only part of the found assets is shown when searching for assets of the specific type
