That is the correct behavior. Adjusting the shift will not move the
low frequency (audio) limit "below" the carrier (e.g. negative). If
moving the shift toward lower audio frequencies would move the low
frequency audio cutoff "below" 0 Hz (into the opposite sideband), only
the high frequency cutoff will be moved.
What you are seeing as "narrowing" is the movement of the high limit
with the low limit "frozen" at "0 Hz".

That's because the cursor represents the actual CW frequency and
moving shift will adjust the response +/- the CW "pitch". If you
expand the CW display, you will notice that the cursor will still
not shift more than "pitch" (e.g. 500 Hz if that is your pitch)
to the low audio frequency side of the carrier/cursor as the shift
is moved lower in audio tone.

the U shaped cursors doing this before. The CW cursors will move either
side of the center line and not change width with the "shift" control.
The width of the cursor does change as it should with use of the "width"
control in both CW and SSB modes.
