More trackpad issues- MacBook Air 2015

Hi, I posted here yesterday about the click on my trackpad failing and after I resolved that issue (so I thought) by adjusting the screw sitting beneath the trackpad & increasing the tension, most of the trackpad works properly aside from the bottom left third that doesn’t register any clicks. I feel like I’ve tried everything at this point aside from replacing the trackpad itself but I’m not even sure that’s the problem because it functions otherwise perfectly. Any advice would be appreciated
