Running happy with rtg vcfeval engine does not result with FP.AL 0

[kubranarci]

Hello, I am experimenting happy running with rtg vcfeval engine, and a potential bug (or an error from my side) took my attention. Running happy with rtg vcfeval engine didnt result with FP.AL 0. Can someone please take a look over my run and give an explanation over this?

I also made a comparison run running without the engine, with default settings:
