Index issue

Hello, I’m getting reports from Google Search Console, that some part of pages connected with your plugin was indexed, but blocked by robots.txt.

Example:
https://sitename.com/wp-admin/post.php?post=xxx&action=edit

The url redirect to admin “edit” page, and should not be indexed at all. Can you check this?
