I use the Razar Tartarusv2. when playing wow. I have my buttons set up and use the same profile in all versions of wow. WoW classic, Wow classic cata, Wow classic SOD, and retail. I have the number 15 key on the keypad  keybinded to the number 2. And all the other keys keybinded to others as well. In all versions of WOW the 15/2 key works. But when in retail it will not. Its not a physical issue because it works everywhere elses used. even in a notepad document, clickiing it will type “2”.  So what could the issue be?
