I just logged into the site with a different browser and I am not seeing the same issue. I was Google Chrome for the deletion of custom posts. Upon signing in Firefox, I didn’t experience the same issue and was able to delete the post. I was about to try the method that you answered in previous posts about custom post type slugs having a space in them and deleting those post types is not possible unless you edit the exported code; edit the content and then imported it.
