Attributes not showing up in Variation

I am creating a store that sells posters and prints.
I have already setup some test products using the poster size as an attribute, and it seems to be working just fine.

I then wanted to add Frame as an attibute, but for some reason it does not show in the variations.

Here’s a screenshot of my attributes: https://screencast.com/t/eygNxV1II

Here’s a screenshot of my variations: https://screencast.com/t/d26mGR9Ec

You’ll notice on the variations screenshot, it only shows my original list of attributes, not new sizes with the word Framed following.

What am I doing wrong?

Thanks!
Nick
