Most likely the default figure style (perhaps the only figure style) in the font is OldStyle figures. You'll want to be sure you are using Lining figures.
OldStyle figures are more compatible with running text and mix well with lowercase letters because they have ascenders and descenders. Lining figures are all the same height.
This is due to the font - there should be a setting in the the Character Panel , flyout menu on the right - go to Open Type - and toggle the last 4 options at the bottom
Peter and Eugene, Thank you both for the quick replies. I may not be understanding very well. But both your answers let me see that maybe I should have set up the character style for the numbering instead of letting it default. I'm using Corbel for the chapter title font. I did not have a character style set, so went and created one using Corbel with the exact same font specs as the Title - Bold, 14 point, 16.8 leading, etc. I then synced across the book and regenerated but it didn't fix it. I played with toggling the four options Eugene -which if I understood you correctly are Ordinals, Fractions, Discretionary Ligatures and Slashed Zero but did not see a change after repeating the sync with all four toggled on - since they were all off. However, I realize I may not be understanding, or since any change means synchronizing and then updating the numbering, maybe I haven't hit on the right option to toggle. Thank you again for trying to help me. I don't understand why two chapters still work - 6 and 8 but 1-5, 7, and 9-12 display below the baseline. Am I not getting it? Or have I misunderstood your replies?
Eugene said the "last" options. He meant the four options at the bottom of the list, but above "Default Figure Style". Try "Tabular Lining" as Peter suggested.
Thank you for clarifying. They were so right. That one little change did it. Who knew. I would have been forever looking for it.
To save anyone else who has this problem in the future and is unfamiliar with that option, here's where it is.
In Character Styles select the Open Type Features panel.
There is an option towards the bottom of the panel labeled "Figure Style".
One of its options is "Tabular Lining."
Once I selected it the problem of the auto generated numbers not lining up with my chapter titles fixed immediately.
Thank you so much Peter, Eugene and Tom for your help with this!

Actually, I only said Lining, and for chapter titles I'd use Proportional Lining if available. Tabular figures all have the same width and are good for columns of numbers that need to align, but proportional figures look better in running text.
