This command lets you remove all of the entries for any list, including the AKICK list for a room
/msg chanserv sop #ConferenceRoom wipe
/msg chanserv akick #spiderslair wipe
/msg chanserv vop #webchat wipe
If a list is very poorly set up, sometimes wiping it and re-adding the entries that you actually want is the easiest way to fix it. Otherwise you would have to delete every entry that you did not want manually.
