I have multiple documents that start with Heading Level 1.0.

Document #1 - Heading 1.0
Document #2 - Heading 2.0
Document #3 - Heading 3.0
Etc.

Every time I open Document #2/3, the Heading Level 1 restarts at 1.0 even though I have already defined it to start at 2.0. I need to know how to fix this so that whenever the document opens it reflects what I need.

TIA
