It's a known issue. Mine is the same.

----------------

On all bands (except 6m) I can increase the power up to 12.0W in steps of
100mW. With KPA3 on "Bypass" (probably the same without the PA) that's the
top end (firmware controlled as expected). With the KPA3 on "Normal" the
amplifier kicks in just over 12W (relais clicks, RF scale changes) and the
display jumps to 13W. Nothing strange so far.
On 6m however the maximum power with KPA3 on "Bypass" is 8W (probably due
to limitations of the LPA). With the KPA3 on "Normal" the amplifier kicks
in just over 8W and the display jumps to 13W. No possible setting between
8W and 13W. This is the strange bit.
