[Elecraft] KX3/PX3 RIT Question

[K3WWP]

When I use the KX3 RIT, I get a red 'transmit' cursor on the PX3 which is
great. However when I press the 'B' knob to reset the RIT to zero, the RIT
resets, but the red cursor remains on the PX3 until I slightly turn the 'B'
knob, then it disappears. Just turning the 'B' knob (without pressing it) to
reset the RIT to zero gets rid of the red cursor as soon as zero is reached.
Everything works fine with Split. Turning off Split gets rid of the red
cursor immediately. I haven't tried XIT to see what happens with it because
I never use XIT. Any ideas what's going on?
