Problem connecting Harmony HUB with Flirc Gen2

[Znapshot]

I'm hosting a homeserver running with ubuntu, now i'm also running the Plex HTPC application on it and tried to control it with my Harmony HUB and Flirc, so i followed the instructions and everything is set up, the receiver is displayed and i'm also able to bind a remote key as a keyboard key. But what puzzles me, when i open the terminal, and press the bound remote button for mapped key "a", no "a" is printed in the terminal. Everytime i set up button "a" and bind it to the same remote control button, ther HUI says "recording successful" any hints on how to solve this issue? When i open the Log and do log the IR input, i can see that commands are recognized, but i cant say anything about those numbers popping up :D
