Did some new test this morning.
Using SpawnPoint_USMC_SP (RHS), Loadoutmanager_USMCxMSV (RHS) and FactionManager_USxUSSR (AR) changed the faction US to RHS_US_USMC and putting RHS_US_USMCeither on the area or, the layer , the Custom title and description are displayed. If the key is only on the slot it's not working
