When searching for hosts with a filter based on a yes/no HW/SW Inventory attribute the search always returned an empty result, no matter which value was selected.

A prominent example is the Cluster host filter (Software > Applications > Checkmk > Cluster): filtering the host search for cluster hosts never returned any host.

All filters that are generated from boolean HW/SW Inventory attributes were affected.

The filters now evaluate the stored inventory value again and return the matching hosts as expected.
