Can you double-check that the project the affected action is in doesn't have a due date associated with it?
OmniFocus will use whichever of the two comes earliest when sorting the project, but we only show the due date attached to the action directly. This has confused a few folks.
If that's what you guys are seeing, let me know and I'll attach your reports to the feature request we have open on actually showing the date we're using to sort alongside/instead of the due date for the action.
if that's not what you're seeing, can you send some screenshots of
- the action before you change it in context view
- the action after you change it (also in context view)
- the project the action is from (in project view)
to the
OmniFocus support address? We'll take a look and see if we can figure out what's going on here.
