Hunting Log vs Grand Company Promotion Request

[Pashen]

I'm a level 53 Bard Archer Corporal in Twin Adders. I've maxed out my hunting log's "Ranks" by completing all 5 listed. Yet the Twin Adders personnel OIC keeps telling me to complete Rank 1 before I can be promoted. I have over 6500 [edit: grand company currency, not gil, as previously stated] of 6000 required for the promotion.

I haven't learned any crafts or professions, nor done any PvP, nor joined any free companies, but the personnel officer doesn't cite anything but the Hunting Log Rank requirement. What am I missing? Apparently, I can't get promoted until this is resolved.

Thanks in advance!
