Firewall doesn't apply changes

i have the problem that the firewall doesn’t apply changes like renaming a rule or changing a portnumber in a rule.
everytime i want to change a rule i have to delete it and to create it anew. (:AGY)
os is win xp pro sp3, admin rights are given
somebody an idea?

I noticed the same trying to edit a rule definition.

In Vista, I seem to be able to edit a rule but not rename it. Looks like the bug in .25 was not fully addressed in CIS.
