It's quite likely the count for OF on iPhone and OF on the Mac are different.

In particular, OF for iPhone can ADD the numbers of Due Soon, Overdue, and/or flagged.

OF for Mac WILL NOT add. If you have overdue items, it is the number of overdue items (only). Due Soon items are ignored.

So take the case of 5 overdue items and 10 "due soon" items. OF for iPhone will show as you've defined it (and can show 15 items). OF for Mac will ONLY show 5 items, and if you complete ALL 5 of them, it will then show the number 10 in orange.

I don't believe either include the number in your inbox in the badge.
