I can't delete a mail addres from a maillist

Hi

I use qmailadmin, vpopmail, ezmlm and qmail-1.03.

I moved my mail server to another server with all accounts. It works any 
problem. ezmlm works too. But I noticed that I can't a mail address in a 
maillist using ezmlm or on qmailadmin. however the existed maillists works.
I checked permission of the maillist. the owner of it is vpopmail:vchkpw
if I removed maillist and readd the same maillist and  then readd the mail 
addresses into the maillist. This time I can remove a mail address from the 
maillist.

How can I fix that case without deleting the maillist ?
