If you bring context view up and then hover over
View -> Status Filter
which option is active? It almost sounds like the Available setting has been chosen. If that's not the case, let us know and we can keep investigating.

Personally, for my someday actions, I just add them to OmniFocus with no start or due date attached. Actions just sit there available-but-not-urgent until I do them, or decide I'm not going to do 'em.

Admittedly, I don't have too many of those actions - I'm sure my system wouldn't scale up well at all if I had more actions in that category.
