I have created a custom Model. However, in the processes of labeling and training it failed with

Model training failure "InvalidContentSourceFormat: Invalid content source: Could not read build content."

and went int a Status failed.

Now I can not delete this model.

Please help with info on how to remove the failed model?

Thank you,
