I have a new version of MS Project, loaded by my company. Using: MS Project Online Desktop, Build 13801.21004

I started a new schedule, entered in all of my outline headings /
tasks / durations / predecessors... I always start a project this way, free-form thought process... then I "Sort" by StartDate with re-numbering... has always worked like a charm, until this version of Project. The problem:

1. Within any given OutlineHeading, the tasks fall in order as they are supposed to
2. BUT... The OutlineHeadings are not in order... Earliest group is first, then last group, and then descending order of groups.

SCHEDULE ATTACHED, POST #2 BELOW...If someone needs to see the schedule, I can send it as an attachment, or DropBox link... if you can help, please let me know what is best.

Muchisimas Gracias!!!
