fullSyncGroups wrong option in drop down

Trying to run a sync - fullSyncGroupings as configured by the add daemon. (did a fullSyncFull which worked fine). But I got the following error (grouper 2.6.8)
java.lang.RuntimeException: Cant find GcTableSyncSubtype from string: 'fullSyncGroupings', expecting one of: fullSyncFull, fullSyncGroups, fullSyncChangeFlag, incrementalAllColumns, incrementalPrimaryKey, fullSyncMetadata, incrementalFromIdentifiedPrimaryKeys,
