I just purchased Dawntrail, via Steam. (If I could turn back time six years I would never have gone the Steam route with FFXIV, but that's besides the point).

In my CD keys there is one entry for Dawntrail - pre-purchase Bonus Content.
For Shadowbringers and Endwalker, there are TWO sets of keys, the other being Standard Edition Content.

I forget - does that second key show up later, after the expansion drops, or is something funky with my account?
