Problem with horizontal scroll on a Logitech G502 Proteus Core

I have a problem with my Logitech G502 Proteus Core gaming mouse and the scroll left-right functions. They do not seem to be working. I have the latest Logitech Gaming Software, all the other functions work fine, except for this one. It is quite inconvenient, especially in certain games, or even Excel files. Is it a problem with my device, or a larger software bug? Is it fixable?
