Please disregard this question. It turns out my loop was wrong, I needed a
<=, instead of simply <. When comparing, it looks like my custom folder is
returned in a different in order depending on cached or non cached mode.
For non cached mode: it was returned 7th (out of 14)
For cached mode: it was returned 14th (out of 14th)
Thanks,
