Think I see the problem on my end. Using JTDX for FT8 and Ft4 and Log4OM for logging. Yesterday I had downloaded the latest version of WSJTX to test and had it running in the background. Have Log4Om set up to scan both JTDX and WSJTX log files and pull into Log4OM... Somehow it messed up the log in Log4OM adding submodes.
If your having Log4OM scan (Monitor) the WSJT ADIF file your set up incorrectly and should follow the method reccommended in the Log4OM user guide which uses the WSJT UDP connections and automatically uploads to all on line logs as the QSO is received. The Log4OM forum is the best place for support as we very rarely check this forum
