Portrait Photos are FLIPPING landscape when I zoom in on them in the Photos app on my Mac

Similar issue, for sure. However, no real solution is offered. The issue is NOT the images. They all opened just FINE (proper orientation). My wife was paging through each one of them and enjoying the experience. Then, she accidentally opened the editing software on one image and continued paging through each subsequent image (blown up to full screen). Now, each of them appear to be "in editing" by the Corel AfterShots 3 software, and each of the images has become affected. When you see the thumbnail, it's FINE. When you double-click on it, it opens in Portrait for a mere fraction of a second, then it flips on its side to fill the whole screen in landscape. If you rotate the image, it keeps showing it wrong. It just makes it go WIDE and stretched. This is a complete GLITCH in the photos app on the new Mac OS - and it is SUPER frustrating!!!

I was trying to show my wife how EASY it is to view and edit her images. Instead, we both got real frustrated!

One other tidbit... I attempted to "edit" some of the images in a different software. When I did, it asked if I wanted to be "done" editing them in the Corel software. I said "yes", did anything I could, and then told the image to "Revert to Original". THEN, the image would stay in portrait mode...

Weird, right???

Help!!! O.o
