Off the top of my head: It sounds like the signal isn't getting through the 250 Hz filter when you have it selected.
Double check that it is installed correctly. Double check you activated the correct slot in the CONFIG menu. The XFIL button will allow you to switch filters without changing the DSP bandwidth.
