ASM policy change not showing as a sync change

Yesterday I updated from 12.1.3.7 to 12.1.4 following the F5 SIRT email recommend to do so. Since then we have noticed that when a change is made to an ASM policy it doesn't change the sync status, and we can't sync these changes to the standby unit. To test the change I booted the pair back to 12.1.3.7 and ran the same test, and again, no change visible and sync doesn't send to the standby unit, so we don't think its anything to do with the upgrade, but it was working fine before this was carried out. Can anyone suggest anything we can try?

Thanks in advance.
