Warping, distorted, overwrapped 360 video output to youtube and mettle player

Distorted "over wrapped" footage.

Hi I have a problem with my 360 video and CG 360 video over wrapping onto itself thus heavily distorting the image and creating a black dot on the top and bottom of the images.  All my other footage is fine.   I'm working with Premiere pro CC 2017,  After Effects and Media Encoder and Mettle to create the CG ..  This only happens with a higher res clip that I've brought in and the CG tutorial of a city block fly through  which I've created based on a mettle tutorial   Skybox Tutorial - YouTube

Here is an example of whats happening https://www.youtube.com/watch?v=QnrLtiJ3-lk&feature=youtu.be

At the end of the tutorial the encoding options on my AE seemed to not offer the flexibility that the instructor has on his  but aside from bit rate adjustments and

changing to CBR I was able to set for youtube etc.

Anyone have this warping overwrapped  issue?  Do you know what causes it? 

Thanks!
