Yep, this has been driving me nuts as well.
It not only doesn’t sort them properly, it uploads them erratically as well. If you have a panel full of existing images, then upload a group of (let’s say 4) images, it loads 2 or 3 to the top, and one randomly placed halfway down the image panel, very bizarre.
Interesting to hear if you switch to the image only view it sorts correctly, could be a big help whilst waiting for a fix.
