IPhone 16 photo adjust colour issues

I have an iPhone 16 pro. I’m frustrated! I click on a photo and enter the style and adjust options and edit a photo to my liking. I use the adjust sliders not the new styles panel. When I click done and it exits the edit settings the photo visibly darkens, the colours deepen and contrast reduces. If I click the photo to go back into edits it goes back to the way I want it.

I cannot think of a way to stop it doing this.
