Sounds like either your filter configuration is wrong, or your narrow
filter is faulty. Watch the "XFIL" section of the front panel display
as you narrow the bandwidth and make sure that it switches to the
appropriate filter slots based on what's physically installed. If not,
use the K3 Utility to adjust the filter configuration. Based on your
statement that you have a 400Hz filter, but the problem occurs at the
500Hz setting, I'm leaning towards configuration issue - you're
probably switching to a slot that has no filter installed.
