Scrivener Won't Stop Doing the Splits

I just figured out how to “Copy Document Link” so I can open a Scrivener project from within Things 3. Pretty cool!

It’s a small thing, but whenever I do this, Scrivener opens in the “Split” window mode. If my last split was vertical, it will open in a vertical split. If my last spit was horizontal, it will open in a horizontal split.

But I can’t get it to open without being split.

Any ideas?
