Custom Sidebar Elements are broken for service queries. :frowning:
With p3 it looks like this
Definition is very easy nothing complex
If i click the 0 services i also get an empty view. After open the filter and press “Apply filters” i get an valid output. Without changing anything.

Strange side effect - active services are shown if they are faulty.

The filter “Service state type” should be the problem.
I will have a look.

Fix will follow with p4, already in review.

I think the search bar is broken. When I move a host to another folder, I can type in the search bar, but it doesn’t affect the results.
