Hi,
I own a logitech g25 and ive found a bug with the sequential (shift up) and (shift down) and with the H pattern (1st) and (2nd)

If you dont know what im talking about,
I hope these pics will give an idea on what the problem is.

It's not a bug. In G25 H-gated 1 and 2 are physically the same buttons as sequential up/down. Use scripts to change buttons automatically.
