Advanced Filter on ClientSide returns (Empty) when pointing to ThisElement

I am using advanced filtering to iteratte through searchresults and filter those. The filter expression works just fine for resulting objects created by the user, but not for other objects. Search privacy rules were discabled for debugging, but this did not help the situation looks like that:

This is the search result (with an attribute of searchDR)

Using the Filtered-> Adavnced ThisObject results in (Empty)

Any help is much appreciated!

Have you completely discarded that the filter condition isn’t responsible for that void result?

By accident, I realised that this seems a bug of the debugger. It seems that the values are not really empty. I had another advanced filter condition via an API call and this call was provided with data even though the debugger stated empty…
