If you run the following command :
#show profile-errors
Invalid Profiles
----------------
Profile Error
------- -----
It will let you know what general config that was pushed from the master controller but that the particular VLAN 10 exist on local1 sbut it doesn't exist in local2 and then you will see these type of errors, unfortunately those can't be removed.
wlan virtual-ap "test1" VLAN 10 does not exist
