Error Trying to Delete Report Transfomation

I have been playing around with Report Transformations and have created many extra unwanted reports.
The problem is now I want to delete the surplus reports. I cant see how.
Also if I clone a report and then decide to edit and delete it I get the following error

Deleting a transformation depends on how it was created.

Go to the Reports tab. Under the Report Transformations group, click Edit for the one you want to delete, then Delete.

Or Settings > Report Transformations > Edit > Delete.

Yep, that was it. Simple once you’ve done it. Thanks.
