Ridiculous Mouse Sensitivity

For some reason, when I try to play Minecraft 1.12 with my Logitech G700s Wireless Optical Gaming Mouse, a slight movement of the mouse will make my character spin around like 3 times? I've used this mouse for past versions, and it's never done this until now. I have my in game sensitivity down to 25%, and my DPI for the mouse at the lowest point, yet it still happens. What is causing this, and if it's a bug, hopefully it's fixed. I've included a short video showing the issue as it's happening.
