Hey, so I recently updated dropbox, and now it's seemingly trying to redownload all of my online only files.

Obviously I don't have that much storage, and I don't even have the option to make them 'online only' anymore.
Everything I've seen online says to go into preferences and use selective sync. I did, and that didn't seem to change anything.
I didn't try to use a different application either, as others mention. I simply updated dropbox and now it's become really hard to access my older files.
Please help me
