[Elecraft] K3 filter setup anomaly

[The Smiths]

Did you make sure that you also adjusted the Config menu for the filter positions and respective widths?  You can't just put the filter in without telling the rig what you have just done. If you don't adjust that, ALL of your other filters will now be wrong as well.
