Upload from Backoffice has no options

Hello,
Today, I was trying to upload some new documents though the back-office and I realized that in the upload window I have no options to choose from; the only ones that I have available are “Name”, “File Upload” and “Tags”. I can’t choose the authors, choose the folder, the state, nothing.

For all the other documents I’ve had all the options available and I had no problem uploading and organizing everything.
I’ve tried to see if there was some changing in the settings but everything is the same as last time when it worked. I tried to change some settings and the problem remains.
I even tried to create a page with a front end upload button and there it works fine, it has all the options! I don’t know what is wrong with the back office part.
I could use some help with this…
