Check your data sub-mode (DATA MD) *one each band*.  The sub-mode
is stored *per band* and it would appear that yours is set to
AFSK_A (LSB centered on the dial frequency) instead of DATA_A (USB).

It is likely that the sub-mode on 15, 17, 12 is incorrect (probably
because your logging/data program set it to AFSK_A when you last
operated RTTY on those bands).
