Project-based perspective - Sidebar different in OS X vs iOS

I have a perspective which uses project hierarchy. Here are the settings:

(Cutoff in the screenshot… Focus is set to several high-level folders; Sidebar Selection is none)

Under each high-level folder, I have most projects “on hold”, with only the ones I want to see this week set to “active”.

I rely a lot on the sidebar to show a simple list of the “active” projects, which I then use to browse to the (flagged) tasks. Similarly, on iOS, I use the sidebar-equivalent view (after the first click on the perspective name), to browse active projects.

**Here's the bug / issue / question:**

I have a project that has no tasks flagged (hooray!):

  • In OS X - this project is listed in the sidebar of this perspective

  • In iOS - this project is not listed in the sidebar-equivalent view of this perspective

Put more simply, the visible project list is inconsistent between OS X and iOS.

Is this a bug? A feature? A simple setting I am missing somewhere?

Thanks for any help!

I am running:

OmniFocus Pro 2.10 (v113.13 r289257) on OS X 10.11.6

OmniFocus Pro 2.20.2 on iOS 10.3.1 (14E304)
