The Delta Resource Membership update schedule will only touch filters that are associated to an active filter via a "Target’.
The Complete Resource Membership schedule will update filters that are associated to policies that are both enabled and disabled.
Some filters have no associations to anything. They are not associated with any update schedules.
If a filter is not updating automatically, you will need to create a scheduled task to update the filter: www.symantec.com/docs/HOWTO21573
Attached is a report you can import which will enable you to see what filters have not been updated in a specified amount of time (in 'n' hours).
Also attached are a couple of queries that may help you determine what filters are updating and how.
Please be advised that all attachments to this document are distributed as is and are not provided as part of the product line.
