Sync Summary Status Sync Failed

Hi all,

I am having an issue with an HA pair that is out of sync. I get the following message when attempting to sync:

Sync Summary Status Sync Failed 
Summary A validation error occurred while syncing to a remote device 
Details Sync error on LO1P-LOBA-252.xxxxxx.pvt: Load failed from LO1P-LOBA-251.xxxxxx.pvt01020036:3: The requested ltcfg_class (profile_scim) was not found.
Recommended action: Review the error message and determine corrective action on the device 

The message on the HA status line is "Does not have the last synced configuration and has changes pending"

Any help would be greatly appreciated!
