Duplicate Project Types in VS 2010

I’m getting duplicate project types showing up in the New Project dialog box in VS 2010 professional. Any idea what caused this, or how to remove the duplicates?

I don’t know if this is normal, but I have duplicate templates in these directories:

So I suspect the “how to remove” could be as simple as renaming the 2nd directory (which looks weird). I’d say it’s come about when you’ve reinstalled something, either the netmf SDK or GHI SDK, and it hasn’t quite “worked”.

Thanks Brett.
I ended up moving the contents of the newer directory to the older directory, and then I deleted the newer directory. This seems to have fixed the problem.
