I SAVed CW NORM2 to include APF. Now rotating the SHIFT control doesn't
remove the wings from the filter passband graphic, as it would without APF.
Thus it isn't possible to tell from the display if the filter is still
normalized to NORM2.
Is this intended?

When APF is engaged, the shift knob no longer shifts the IF/DSP -
it moves (shifts) the audio peak within the IF passband. Thus,
the IF/DSP response display does not change. Note - adjusting
the WIDTH control will change the width of the center portion
of the display as the IF/DSP width changes
Recalling NORM2 changes the APF shift back to its normalized setting.
But the wings don't change when that happens.

The Wings don't change as long as APF is on. If you saved NORM2 with
APF on, recalling NORM2 turns APF on (and displays the wings).

That's all.

The wings are already set at maximum width and the center changes
to show the selected DSP width. Shift does not move the DSP peak
when APF is engaged and the display reflects

After all, this is supposed to be a representation icon of the APF,
isn't it?
No, it's a reflection of the IF/DSP just like in all other modes,
