When we change values in the media_sort field everything works fine. If we change the value in one or more fields or all media_sort fields everything works fine.

When we want to replace an image via file input, it will not work as it should, because it will only upload images but not write to the database.

If we modify all the pictures, in this case all 5, everything will work properly. They will upload 5 pictures and their names will change in the database.

If I change only the first image, everything works fine again.
