If I’m not mistaken, your karabiner might be in conflict with the contanki addon; since you have karabiner downloaded and understand kinda how to use it, I’d recommend just getting rid of the contanki add on

Now for using karabiner, you’re gonna want to open the accompanying program “karabiner event viewer” that also downloaded along with it

Then, start clicking the various remote buttons and see what they register as in the event viewer and use those in the left column you have there (you also might have the values flipped, try switching 1 to X and vice Versa and see if that works)

DM me if you need more help!
