I'm having a problem with the B4 filter.
I have it turned on so that I should not see any calls worked B4.
It does not always work correctly.
I also have CQ alerts turned on.
Some calls are still highlighted as a new CQ call even when shows on the same page as worked B4 like the call K5DGC
in this capture. This is not the first time this has happened. I've called stations and had them tell me that I worked them B4.
Is this a bug or is there a setting that I need to change.
