I'm trying to setup my Inteset Universal remote with amazon fire tv gen1. Using the Flirc software for Mac to set it up. During setup when i reach the point where im supposed to program the down button it tells me i've already programmed it. So i skip it. I'm prompted to program other buttons but it keep telling me that i've already programmed that button. I tested it on the amazon tv and the up and down button on the remote have the same function though they are 2 separate buttons. I tried clearing the config multiple times and deleting buttons but it seems to think that those 2 buttons as well as others are the same. Can i not program Flirc with this particular universal remote? Anything i can do to fix this?
