Drag & drop folders no longer uploading as a standalone file.

Recently whenever I drag and drop a folder of pics from my desktop into my Dropbox, Dbx automatically uploads it into another existing folder instead of adding the folder in as a new folder into "All My Files". Why is this happening? It's very frustrating as I then have to search every folder I have for the newly uploaded folder. There also seems to be no way to move the newly uploaded folder out of the existing folder so that it will appear in "All my files" Someone please help! 

I should mention I used to be able to drag & drop folders of pictures from my desktop onto the web-based homepage and dropbox would add the folder as a standalone folder with no issue. And I'm not dragging it and then dropping it into an exist folder. I drag it to right above the other folders and drop it. so there's no way Dropbox could be interpreting that I am trying to drop it into an existing folder.
