If you have BHQ Quinta, you might check to see if the initial Quinta apparatus volume has a series tag. Mine didn't. I never noticed until I started having multiple Quinta apparatus's in my layout.
Biblia Hebraica Quinta
If you remember, FL shipped the initial resource with a bunch of Bible books. Then after that, they issued individual volumes.
So, for example, if you're in the Judges apparatus (individual volume), and switch to Ruth (in the initial volume), it'll open another panel of Quinta apparatus.
Now, FL wasn't entirely consistent; Deu is both the original volume, and the separate volume. But it seems to work (assigning all to the Quinta series).
