Why is my Linear FOV GoPro Hero 4 Black video distorted at edges?

I installed the latest firmware as of 09-APR-2019 to my GoPro Hero 4 Black.

 

I recorded video in 1080 60fps in LINEAR FOV mode with ProTune enabled. Why am I seeing lens distortion at the edges? For example

look at the front wheel of the car.

 

I have Adobe Premiere and can get GoPro Studio how can I remove this? i don't mind losing some of the frame.
