I'm new to new to creating stock footage, why does it say there are quality problems with these images?

 I took these images on my trip to Vietnam with my Sony a6400 (first image (resolution 6024x4024)) and DJImini 3 (last 2 images (resolution 3840x2160)).

I’ve edited them and uploaded a slightly compressed version to adobe stock to be in the 45mb limit. After review it says there are quality problems and i’m not sure what it is. Are the images just bad? is the compression messing with the check? something else?
