Often the 'r' key acts as the 'up arrow' key when in the crafting mode, it will change the menu up a tier, when I am trying to select an item to scrap

the tab key fails to work sometimes, pausing and restarting usually re enables it, but Have had to reboot a few times in 100 hours of game play due to loss of all key functions

I have a G510 in native mode (none of the logitech software loaded)
