If you create a Device then an Activity and then change a button in the Device it doesn't carry over to the Activity. Your best bet is to delete any Activities the Foxtel is in till you are finished setting up the devises. Either teach the X1 all the Foxtel buttons in IR as a single device or as mentioned before have 2 Foxtel Devises (one Bluetooth and the other the missing IR codes) then create a new Activity. If you went down the single device route you are done. If you went for 2 devises then in the new ACTIVITY you need to allocate the IR functions to the relevant buttons. Remember Devises mode is only really for setting up the X1, for daily use it should be used in Activities mode only.
