Somehow filtered entire library by vr games without filter, how to undo/recreate?

I somehow made the steam library hide all non-vr games but display like normal, and the category game totals now show a remaining count/total. There are even categories that arent showing up in this screenshot because they have no vr games.

I've never been able to do this before and would like to know how to recreate it.
I already fixed it by just restarting steam but being able to do this intentionally could be useful since the library filters only take effect in the side bar and stop showing categories normally.
