My Cloud Home Time Machine backups

Somehow, in the past, I set up my My Cloud Home to be used as a Time Machine backup for my MacBook Pro. I recently upgraded to a new MacBook. The Time Machine is still visible on the My Cloud Home but I cannot remove a large older backup. It’s called a backupbundle. I’d like to be able to free up that space (around 300 GB) but it says it isn’t able to delete that file. It is not marked as Locked and all permissions are available.
Is there anything I can do?

Hello,

Please refer to the following KBA article: How to Delete a Time Machine Backup on a My Cloud or My Cloud Home
