OneDrive uploading notification keeps growing

I have 40GB capacity on OneDrive. Recently I updated a lot of files and folders. My main folder is now 18.5GB

OneDrive started uploading to sync the folder, but it now shows uploading 27GB of 27.4GB and both numbers keep growing and growing. The files remaining stays at about 200 and doesn't go down.

This is more than I actually have in the folder, how is this possible? And when is it finally going to sync the final 200 files?

I am using regular OneDrive linked to my school account, and Windows 10. My upload speed is 10Mb/s
