Hi there,
This has been covered a lot. You will not encounter SEO issues on this if you do not link to it. SEO report tools, scan a site and look for all things that may cause SEO issues, and they can report that, and an SEO guy could blindly say that is SEO issue, but if you do not tell google about it then they wont link to it.
A 301 redirect would paint over the problem as it were, but the real problem is that your linking to the home page in different ways on your website. You need to go through it and fix that up. That is the real problem, once you have done that, it will take a little time but google will naturally degrade the other links it used to find and this will go away.
