[Elecraft] K2 Transverter TRN3 and TRN6 setup problems

[W4sc]

Anyone having this problem.?? Solution ??

After setting up the TRN3 and/or TRN6 parameters in the K2 and returning to normal operation, as soon as VFO knob turned the frequency on the display go to what seems to a randome one, AND VFO input is ignored (?) as dispaly is "locked".  Other TRN bands (TRN1, 2, 4, 5) work OK.

KX60 installed, but this happens with/without.

Thanks
