Mouse not responding/interrupting?

Hello all, I'm currently having issues with my Logitech M705 mouse and my other mouse (I dont know the model). My problem is that whenever I do something in-game that I have binded to my mouse, I.E., when I hold left click to aim down sight, it will stop aiming down sight without me letting go of the button. Or if I hold down MB5(?) to sprint, my character will start then stop running and I have to press down the button again. As far as I can tell, I am not having this issue with any other games (such as League of Legends or CS:GO). I don't want to have to buy a new mouse because I'm not entirely sure it is the mouse's fault because I have tried it on another Logitech mouse and it still does it, but not to the same extent. Has anyone else encountered this problem, or might even know a fix? It's extremely frustrating and makes it partially un-playable. Any and all info on this issue is welcome :) thank you.

P.S., My mouse drivers are up to date according to my computer and this happens on GTA Online as well as in campaign.
