Heading 2 Numbering Problem

[consenti]

My outline heading 2 formatting seems corrupted. I've read the shauna kelly site but that didn't solve the problem. When my Head 1 advances to 2.0, 3.0 etc. the Heading 2s remain as 1.1, 1.2 etc instead of 2.1, 2.2 etc and 3.1, 3.2 etc. When I try to click the "previous level number" box to indicate "level 1" although it shows level 1 as an option, it won't allow me to click it. I don't know if that has anything to do with this numbering problem. Any suggestions? Thanks!
