Continue to get 9871 online maintenance overlap errors after adjusting cleanup schedules

After noticing 9871 errors for overlapping cleanup maintenance schedules I adjusted them accordingly, allowing for 15 minute intervals between each start time.  However I continue to get the 9871 errors:

"There is an online maintenance overlap for database "Fifth Storage Group\Shared-Mailboxes".
Please revise the online maintenance schedule."

When I output the schedules from the SCC mailbox server (below) I don't see the overlap in schedules.

What's up?

Thanks,
