Oblige with Obaddon: first map always produces few enemies

[Darkbeetlebot]

I'm having an issue with the most recent oblige+obaddon settings which is causing map01 to always produce FAR fewer enemies than every other level. I don't know which settings are influencing this or if it's a bug with obaddon itself. This doesn't occur if I turn obaddon off and generate with vanilla oblige. The attached screenshots show the settings I'm using. I should note that I have actually tried changing the monster amount from progressive to mix-up, then to the highest possible setting. No change caused the first level to generate more monsters. The only thing that seems to have some sort of effect on it is the linear levels setting, but that's only true sometimes. The only time this doesn't happen is when I choose to only generate one map, but this isn't desirable for a whole host of other reasons.
