Move a file from preview mode and make it close down

This was working on Dropbox before but it is not working anymore. You should bring this feature back. So the problem we have is when we move a file from the preview mode. The file moves and get a new location but it is still shown in the preview mode in the mapp it got moved from. It should closed down and you should see the next file in the mapp. The next file in line. Since we started to use Dropbox. For over a year ago it has always been like this. Say you have ten files in a mapp. You open up the first file in the mapp in preview mode. You can see the file and then you have arrows with one of ten. This shows that it is ten files in this particular mapp. Now when you move file number one to another mapp it will move and close down. You will now see the file number two in the mapp in the preview mode. Automatically. But now it will be shown one of nine instead in the mapp because we moved one file. And then you repeat the moving file by file till you get the last file in the mapp. One of one. But now you still see one of ten though you moved all files from the original mapp and it looks like all ten files still are in the mapp. Though they have all been moved to a new mapp. Now you can move all ten files one by one but you still think they are still in the original mapp though they have been moved.
