Google indexing wrong homepage!

I've got an issue in that Google is trying to index 2 homepages, so for me that is www.adesign.ltd/ and also www.adesign.ltd/home. This means that the latest version /home isn't being indexed, and Google is displaying an error as an alternative page with proper canonical tag found. Is there a way I can say remove the canonical tag from the root folder version with a code injection or similar so that the /home becomes the only one to be indexed?

Maybe I misunderstood. Is this your issue?

Yes that's the issue - I should have put a post on there, was hoping this might have been fixed by now or a new solution under 7.1 was available
