Set Expression Filter not working

[alliedarmour]

Hi! 

I'm new to Qlik Sense for my new work and trying to understand why my filter critera in my set expression is not working.

Im filtering records based on a certain catalogue which should be always selected including the current selection and two aggregated values.

This is my set expression:

Count ({$<Leistungskatalog={'EBM2000+'}, FallBewegungKey = {"=Aggr(Count(ICD), FallBewegungKey) > 0"}> + <FallBewegungKey = {"=Aggr(Count(Leistungsziffer), FallBewegungKey) > 0"}>} DISTINCT Fallnummer)

The important thing is the first part where the record set should be filtered on the EBM2000+ catalogue. The correct count which should appear is 290, which indeed is correct when I manually select the filter option:

But when I clear the filter option on the catalogue, the filter doesn't seem to be applied by the set expression and the other catalogues are shown aswell:

Where am I wrong here? Thanks for any help!

Unable to grasp much but I think your set expression should just be
Count ({$<Leistungskatalog={'EBM2000+'}, FallBewegungKey = {"=Aggr(Count(ICD), FallBewegungKey) > 0"}>} DISTINCT Fallnummer)
,
Because in second part of set analysis you didnt define that  :-
Leistungskatalog={'EBM2000+'}
