Update - My brother received his Flirc the other day and I set his up exactly the same as mine except I did not map and back command - I left the Flirc Kodi settings exactly as they were when the device was added. His Harmony One Exit button sends a Return command to the Flirc, just as it was automatically added, and it works fine. I then erased everything involving the Flirc and Watch Fire TV Activity in the Harmony software and erased any commands I set in the Flirc program, then re-added everything all over again and tested, and I am getting the same result as I had before! I does not make much sense! The command is correct and the fire tv does go back a menu, it just seems like it is processing it in a way that makes it register for a fraction of a second and sometimes it jumps back 2 steps. I guess I will have to use it the way it is.
