Gparted and Calamares disagree on partition size and distribution

I am trying to install from the latest (downloaded within the last week) 4.9 64 bit ISO. I can boot into live fine, everything seems to work for the most part. However, when I try to install from live, calamares does this:

Side by side with gparted(correct info) and calamares(incorrect info) and I cannot figure out why.

As a troubleshooting step of sorts I tried using the other installer and that just plain crashes. Something is going on but I don't know if it's actually a calamares issue or if the solution lies elsewhere. I've got a post in at the support forum but it is still awaiting moderator approval as I write this. Any help is appreciated.
