My Basic account shows 2.6 TB “shared files” but I cannot see or leave any shared folder

Hi,
My personal Dropbox account ([removed]) shows 2.64 TB used out of 2.5 GB.
The storage page says that the space is used by “Shared files (2.6 TB)” but I cannot see any shared folders in my account.

I am not part of any team and I cannot find any shared folders under the /sharing or /share pages, or anywhere else in the interface.
My own files are only around 190 kB.
I also cannot change owner settings or leave any shared folder because nothing is visible.

It seems like my account is linked to an old or hidden “legacy shared space” which is not visible in the current interface and cannot be removed by myself.

Could a Dropbox Staff member please disconnect this hidden or legacy shared space from my account?
This is the only way to restore the correct storage usage.

Thank you very much.
