Your operation is as expected. Note the information from the release notes for the current (beta) firmware:
> * AM DSP BANDWIDTH DISPLAY NOW SHOWS *AF* BANDWIDTH, NOT IF. > We originally showed the IF bandwidth in AM mode since some > operators might be thinking about the underlying AM-mode > implementation (i.e., the IF bandwidth has to be twice the > AF bandwidth in this mode). But this was causing a lot of > confusion, and was inconsistent with the way the DSP bandwidth > control works in other modes, where the *AF* bandwidth is > displayed. Also, LO and HI CUT show AF cutoff points - not > IF - even in AM mode. So we now consistently define the > function of all DSP controls as showing AF frequencies/ > bandwidths. 73, ...
