In that case, you need to reconfigure each Xlate (The File menu item then Reconfigure in the Xlate Configurator), then you can cycle the processes in each site in order to load the reconfigured Xlate into memory.
I think Purge Caches at the thread or process level will also cause the refresh of the reconfigured Xlates.
