You did a wrong setup to WSJT-X. Think you´re using JTalert to check something as worked b4,
new DXCC or something like this. This means that JTalert must have logging enabled. If not it
can´t check the database.
If you use JTalert disable in Log4OM the UDP ADIF_MESSAGE for WSJT-X (or JT-DX) and you will
have only one entry per call. But this is stated also in our Users Manual.
