[Dxbase] LOTW Upload Issue

[Crownhaven]

Sending to both groups.  Not sure if we have moved to IO or not. In any 
event, did an upload to LOTW.  Used regular procedure, signed with 
certificate and sent it on its way.  Three QSOS were rejected.  Here is 
basically what LOTW told me.

21.265

80M CW

When I checked my log, all the info is correct.  Where did the 21.265 
come from?

Same thing basically happened with two other Q's.  One on 40 meters but 
freq kicked back as 28.891

Another on 17 meters, kicked back as 28085.  All CW.

Any thoughts?
