Whenever I try zoom in or out on my laptop the cursor jumps around the screen?

Hi all, so I play the sims 4 on an HP laptop and to zoom in or out of the screen I use my mouse pad but recently whenever I try this the cursor just jumps around the screen and won't allow me to zoom in or out. I know there are other ways of zooming such as using the bar above the camera options or using ctrl - or ctrl + but it is just more of a hassle than using my mouse pad. I do have quite a few mods installed in my game such as UI cheats and MC command centre and have some custom content installed but I don't think this has anything to do with this. I have read through a lot of complaints like this but none of the answers worked for me, I have my camera settings on Sims 4, not sims 3 and I don't think any of my settings have been changed. If someone could please help I would be so grateful because this is really annoying me and making me not want to play the game because it is more hassle. (I have also checked, this is nothing tod o with my laptop because I can zoom in and out just find on other games, browsers etc it just doesn't work in sims 4)Thanks everyone.
