[Elecraft] P3 water fall reversed on 6 meters only ?

[tony leonardini]

A upper sideband signal show up on the lower side & a lower sideband signal shows up on the upper side.  Dose not matter which ssb side is selected on the K3 the transmit signal is reversed.    All other bands display the correctly in the water fall.
Have a K3s /P3 and K3 /P3, ALL setting on both K3’s/P3’s are the same.
Do not know when this started just noticed it on this last 6m opening, this K3 normally has either the main or sub setting on 6m.
Any ideas would be greatly appreciated   wa6qmq
