Apple trackpad wont track on small part?

[miqrofella]

Hi. I just received a macbook pro 13 inch, 2016, without touch bar. I bought it 3 months used, since I got a great deal on it.
Anyway, it is in perfect shape, except for the trackpad. Part of it wont track, like a small "strip".
Here is the video to demonstrate: https://www.youtube.com/watch?v=GugxsiPSlW0

As you can see, on that left side, small part wont track, and it's annoying as HELL.
Any ideas? Or just return it to the guy who sold it to me?

Most likely you just found out why you got such a great deal on it.

Haha, probably. Will take it back later today.
