Google sitemap

I uploaded my sitemap to Google and it seems to be indexing now. But I have a question about it. For testing I first have placed the website in the folder called /maridonbv/. Now I replaced it to the root. For all existing links I made 301 redirects in a .htaccess file.

But now I have a lot of 404 errors in my google sitemap dashboard. I already have edited the robots.txt file with disallow the folder /maridonbv/ but the errors are not gone.

Does anyone have any idea how I can fix this?

Also the filters (with the hash code) are placed into google, is there a way to block the hash code for indexing?
