3500yl protocol and multicast filters weirdness

Hi,

We've got a 3500yl-24G-PWR running firmware
K.13.49 and with the following filters
currently defined:
filter protocol ipx drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5
filter protocol appletalk drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5
filter protocol sna drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5
filter protocol netbeui drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5
filter multicast 01000CCCCCCC drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5
filter multicast 01000CCCCCCD drop 3-4,14,20-21,24,A3-A4,Trk4-Trk5

We are having issues editing the filters.
Any attempt to modify or delete a filter
returns:
"Invalid value."

3500-0(config)# no filter protocol ipx
Invalid value.
3500-0(config)# filter protocol ipx drop 1
Invalid value.
3500-0(config)# filter protocol ipx drop all
Invalid value.
3500-0(config)# filter protocol ipx forward all
Invalid value.

An other 3500yl (3500yl-48G-PWR with same
firmware revision) has not this behaviour
and accept all the previous commands.

Does anyone have any clue ?

Thx
