Not sure when Philippians became part of the OT?

All those auto bookmarks in the middle actually come from the NT.
-- Now this is weird, or should I say even more weird: I just opened the NRSV to see if it was a resource issue. I saw the same thing there -- but when I closed the NRSV tab on top of it, Bibel 82 suddenly looked OK. Unfortunately, closing and reopening either Bible brings the incorrect marks back.
