How to remove staging Urls from being shown in MOZ as critical crawler issues?

[Strausberg]

Hi MOZs,

A few months ago we were updating our website and used a staging site to do so. Soon after we realized that it was indexed by G and shown in Search so we removed it to be indexed. The staging site has since not been visible in search except for 2 links that I just found out about today.

My question is how to remove the staging site URLs being shown in MOZ as crawl issues or remove completely? I want to do this because the digital reports are connected to MOZ and it shows there are currently more than 400x 4xx errors which are all because of the staging URLs. I already marked to ignore the issues but they are still showing in.

Any help would be much appreciated!

Thanks
