Help!! All of the clips are negative

Okay  - first of all, I am a Premiere newb... I'll admit that, but I've used quite a few editors before - Pinnacle, Corel, etc.

I have a fresh install of Premiere Pro, and right now, I'm just playing around trying to figure it out... watching YouTube and all of that. The problem is that EVERY SINGLE clip that I import - no matter how I import them (dragging and dropping, importing them, using the media browser, etc) - they all import with the colors negative... and that's not even 100% accurate - the browns are purple, the blues are yellow - but the greens are actually green. Figure that one out.

I can pull the clips into the time line, trim - add transitions - export the sequence... and the final exported video looks fine. All of the colors are correct in the exported video. Even in the clip library - the colors are correct until I hover the cursor over the clip and scrub in the media library... then they turn the weird negative colors.

The biggest problem is that I can't do any color corrections on anything because I can't tell what the actual colors are!! You do any kind of adjustments and the purples turn more purple - but the purples are brown. I've got a little bit of a sunburn and so my face turns blue - I look like a stinking smurf!!!

Again - this is a brand new install of Premiere - it's on a brand new computer that I just built. I'm not having any other issues with colors on any other apps (that I've found yet). It's a Ryzen 1700x CPU - 32GB Ram - Vega 64 Video card - Samsung EVO960 SSD...

Help...
