That's right, you don't.

RTTY in AFSK A is a different animal from PSK31 in DATA A. In AFSK A, 
the K3's dial displays the actual Mark frequency of the RTTY signal, not 
the BFO or suppressed carrier frequency as in DATA A. The expectation 
when clicking on a signal peak in the panadapter waterfall is exactly 
the same in AFSK A as in CW or FSK D; you would expect the rig to tune 
directly to the chosen frequency so that you can hear the signal at your 
chosen audio tone (set by the K3's PITCH setting).

The mitigating factor for me personally is that I never click in the 
panadapter window in RTTY. I do all my tuning either with the radio's 
tuning knob or from the keyboard. My mouse stays in my receive text 
window - I left click to copy a call sign or exchange, and right-click 
to send the next message or log the contact. Since I installed NaP3 v4 I 
have never once clicked in the NaP3 window to tune in an RTTY signal, so 
I had never seen the problem Pete has reported. Once I tried it to see, 
the problem was immediately evident, but given the way I operate (which 
I believe is not unusual for RTTY), this bug in NaP3 does not affect me.
