If the transmit audio is fine, then maybe he doesn't want to mess with the
BFO settings for position FL1.
Only the BFO settings for FL1 position are used for transmit, regardless of
what filter position (FL1, 2, 3 or 4) is being used in receive.
Have you tried other FL positions? You can adjust the BFO frequencies for
SSB FL2, FL3 and FL4 to adjust the "sound" of received signals without
affecting your transmit audio at all. Select OPT1 for each filter, then
adjust the BFO frequency for the audio quality you want.
Since your transmit audio reports are FB, I'd suggest a starting point would
be to set FL2 to use the SSB OPT1 filter and set the BFO frequencies
identical to FL1. Now FL2 should sound just like FL1. With your frequency
probe in your BFO test point, you can tune in an SSB signal, go into CAL FIL
in your menu and, while listening to a signal on the air, adjust the BFO
frequency for the best sounding signal. Repeat the process on a signal on a
band using the opposite sideband.
This will not affect your transmit audio at all.
You can do the same with FL3 and FL4 if you like a variety of positions.
It's sort of like "passband tuning". Or you can switch FL3 and FL4 to the
variable bandwidth (CW) filter and set it for narrower bandwidths to provide
better QRM rejection in tough conditions, etc.

Remember that your filters are also used on transmit (OPT1). So go back and
redo your filter aligment per the book and preferably using Spectrograph.
This is most likely where your problem lies.
