N1,
Go into preferences and review the "auto-enter" selections. Auto-enter is used to automatically crossfill data. IOW, if you are an airline captain, you would have PIC checked, as every flight you do would be PIC. It could be that Simulator is selected as an auto enter field.
As far as the :54 to 1:00 is concerned: are your out and in times >:54 min?
