Bright images appear dark on timeline

I am making a quick video. The videos were HDR taken with iPhone. I have set up my project with the color range recommended for HDR. I want to have a still image in the project that I have added as a background for part of the longer video. It is just a photo taken with my iPhone and the info for the jpeg says it is in the RGB colorspace. When I add it to my project library, it looks fine. When I drag it to my timeline, it looks fine sitting there in the timeline. However, when I play my project, it is way too dark. Running current and updated MacOS. Any thoughts on why this is happening?
