In general you shouldn't edit images before upload. They are likely to lose their tag data. You can do color corrections if you must but you have to make sure the EXIF and XMP data remain intact. Pixels should not be moved.
If they are it is likely going cause accuracy issues overall. It might be OK if it is just a couple of images. It may work but it won't likely work well.
If you use the rubber stamp tool that you used there which duplicates features it will probably cause other issues and the elevation map will possibly have a spike or flat spot in it there due to the mismatches.
