My modded unit won't unlock in campaign mode

[Ambigatos]

I've recently modded my first two units, however one of them will not unlock in campaign mode once I build the correct building. Both units are available in custom mode, and my one unit is perfectly fine in campaign, but the other simply won't unlock. I've tried starting over from scratch, but no matter what I do it will not work. I've gone over it several times with a fine tooth comb. I don't understand why one of my units work in campaign but the other won't.

The unit I'm having trouble with is the one I have set to be recruitable with the "barbarian artisan major bronze 2." I'm wondering if maybe there is an issue with this building in the PFM or if anyone else is experiencing problems with their units not unlocking properly in campaign.

Thanks much.

Problem solved. It was a duplicate key number. Noob mistake.
