I'm using biblatex-chicago to manage citations in my dissertation. I often cite a multi-volume collection, Foreign Relations of the United States, for which there is an accepted citation format. I've created a customized bibliography driver, @archive to mimic this format, but there is one remaining error I can't fix. The MWE:

Resulting in:
That's exactly how FRUS citations should look in chicago-style, with the exception of footnote 4. Notice that when I repeat the citation for FRUS 1961-63 in footnote 2, it gives me an ibid and a postnote, as it should. Likewise, in footnote 3, it is the first instance of a different FRUS volume, so it gives me the shorttitle for the parent, followed by the shorttitle for the child, the volume, and the postnote. But when I repeat the citation for FRUS 61-63 in footnote 4, it reverts to a completely different style.
What changes do I need to make to have footnote 4 look exactly like footnote 3?
