This is the way how it works. If times counted different from the candidate total the race is grayed out. You can skip betweene races and press OK button, but if there are some unbalance races then warning message is displayed and first unbalance race highlighted.
There was a bug when after closing warning message 'Race Counts Inconsistent' race times counted overwrites with cards times counted even 'Use cards cast for eace times counted' checkbox is unchecked. This has been fixed.
