Touch Pad Clickable Key Feedback Is Weird

I recently bought my Dell Inspiron 15 5584. I am facing an issue with my laptops touch pad. The touchpad is overall smooth and all the gestures work perfectly fine but this is not the case for its touch pad buttons. Sometimes when i do a right click on my laptop it proceeds with a left click. In order to avoid this i have to press in between of left and right keys of my laptop which fixes this issue for the time being. Another problem is that my right click produces a proper sound and it feels like i am pressing a proper button but the left click is quite shallow and the sound is not that proper as well although it works. 

Help will be highly appreciated.

Thanks,
