Premiere Pro Doesn't Playback CineForm footage Properly.

I recently shot a project in 4K using the Panasonic GH5 (three camera shoot). To accelerate my post process I converted all footage into 1920x1080 GoPro CineForm YUV 10-bit as 1080 will be my final output so it allows me to recompose some shots and add digital zooms when needed. Everything worked out PERFECT and much faster specially 'cause I'm editing using multi-cam for the different takes. But that only lasted nearly a week...

One day when I opened PP all my footage looked double as if picture in picture/mirrored during playback and paused. I googled left and right and haven't found a solution. For some reason it seems like my CineForm codec may be broken? if that's even a thing... Even when trying to playback inside of Media Encoder, the footage displays the same.

I thought my processed footage was corrupted until I watch a clip on my laptop which has the latest PP installed as well and the very same clips look just fine. I cannot recall doing anything to PP on my desktop for this to have happened. I thought that maybe I could edit like that "whatever" and then export my final sequence as my laptop reads the files just fine. But it happens that if I output anything it actually prints as it so when I took an export to my laptop the video comes out with the mirrored error type look.

My only way around this now is to reconnect to the 4K footage and work 10x slower than I was. I bought me some time to deliver the project so hopefully someone has come across this issue in the past and has some guidance.

I understand that the CineForm comes with Premiere but is there any way to somehow reinstall the codec? Should I delete and reinstall PP and Encoder?

ANY SUGGESTIONS WILL HELP!

Bellow are screen shots that show:

1. Preset settings I used to convert the footage.
2. The way that PP and Encoder display the CineForm footage.
3. My desktop specs.
