Incorrect frequency logged.

When I was first using my 6600M I would open up four panadapters, A, B, C and D. I would have A on 20 meters, B on 17, C on 15 and D on 12 meters. Therefore while working stations on 20 meters I could watch the other panadapters for signals. If I saw a signal I wanted to work on B, C or D panadapter I could simply click on TX on that panadapter, work the station and log it. My log (either Writelog or N1MM) would log the contact with the correct frequency for that panadapter band. All good.
Now when I move the TX from 20 meters on panadapter A to B, C or D, work a station and log it, the log will always record the 20 meter frequency of panadapter A, not the frequency of the panadapter that I have just worked a contact on. The same happens when I use either Writelog or N1MM so I think I must have changed a setting in the Flex somehow. Any ideas on how to restore the original setup? Windows 10.
