Newly Purchased Commentary on Bottom of Commentary List in Passage Guide

Hey guys,

I recently purchased O'Brien's Hebrews commentary. However, in my passage guide, it appears at the very bottom of my commentaries list. (I had the same problem with Estes' Handbook on the Wisdom Books and Psalms.)

I know I can solve this by prioritizing the commentary. However, I'm curious if there is another solution, or at least what its cause is, so that I can avoid having to prioritize commentaries.

I'm trying to keep my prioritized resource list relatively short so that it can function something like a quick-reference in addition to the Logos prioritizing function. In short, I don't want to clutter my prioritized list with tons of (or any, for that matter) commentaries. And interestingly, with other commentaries I've bought, they had always appeared at the top of my passage guide list. So, I'm wondering why that didn't happen in these two cases.

Any help is appreciated. Thanks!
