Can't use OneDrive on Mac, my folders are in another cloud service

Question

I tried to synchronise my Mac with OneDrive, then I got this error message.

Then I found out that both Desktop and Documents folders are stored in Dropbox like this.

I don't have Dropbox application installed on my Mac. I logged in to the Dropbox webpage and checked the sync settings. There was no Mac connected.

And under the folder Dropbox on my Mac, I only have these files.

How can I fix this problem???

If you don't have the Dropbox desktop application installed, there isn't much I can suggest. In the app, you'd have the option to disable Dropbox Backup, and the folders would return to the default location.

I don't think so.. I tried several things, but the strange thing is that the folders' original location is shown under DropBox folder, but if I enter the folder, there's none of those folder.

I even tried Terminal to change the directory path, but for some reasons, permissions are denied, etc. and there are so many errors without any success. I successfully changed the location of the download folder and I can't move it back to the original main folder either.

Are you able to restore the default location of those folders from within Finder or the Mac OS settings?
