Log4OM

Hello eversione, I have these settings:
JTDX
Primay UDP server port 2237 with the three items on the side checked
LOG4OM
UDP inbound 2237 (JT MSG) from JTDX
UDP inbound 2238 (JT MSG) from GT
UDP inbound 2236 (ADIF MSG) from GT
GRID TRACKER
Received UDP MSG 2237
Forward UDP MSG 2238
in logging (enable) 2236
Everything works regularly, but when a QSO is logged with an American station (it seems to happen only with the USA) the CQ zone is always n.5.
Thanks for any suggestions
Best wishes for the upcoming holidays
