I'm almost positive that this is by design... Map Maker, Orion Report Writer, etc are all managed from the main Orion Server.
I'll double-check in the morning.
This is by design. All map making, report writing, etc is done via the primary poller. That being said i would think those links in System Manager on any aditional pollers should be removed so as not to cause confusion.
PS: when you create any new maps or reports dont forget to copy them over to the Adtl Web Console. Also if you create any new custom properties you will want to copy the OrionReportWriter.Schema file as well or any reports and or filters etc will not work from your adtl web console.
