Problems creating a darabase

I am still trying to ceate a backup of files from my local disk to Microsofts one drive.
I create a backup configuration without any problem but I cannot run a backup. I get … Found 6 remote files that are not recorded in local storage, please run repair. I ran repair without success.
What can it be?

Did you point multiple backup configurations to the same remote location?
Backup jobs should be stored in separate folders in the remote location (Onedrive).

You apparently hit the nail on the head.
I deleted the configuration and pointed a new one at a new directory and it worked.
I did also try just changing the directory to a new one in the existing configuration. This did not work.
