There is nothing, other than corrupt firmware/faulty EEPROM, that could cause this result on a recent K2. Even then, it would be difficult to imagine firmware errors that would result in a selective failure on 10m, as there is no reason why it would need to do a table lookup, based on band, when setting the synthesizer ratio. Older K2's needed calibration of the reference oscillator tweaking (CALL PLL) on different bands, but modern ones just proportion the corrections from those on 40m. I suppose it might still construct seperate tables for each VFO range, and one of those may have been corrupted. The only user tweakable factor that might cause an apparent band sensitive error would be a wrong calibration of a filter. However, that would affect all bands, although the fault would switch between LSB and USB when you pass the point where the IF inverts, but there is only one place where that happens. > correct it? All other band are right on the money.
