Is this on the phone? You may want to open up the settings screen and check your "in contexts, show:" setting. If it's set to "available", try switching it to "remaining". Does that make the missing actions visible?

"Available" will hide actions whose start date hasn't arrived yet; "Remaining" shows uncompleted actions regardless of their start date.

If an action started tomorrow morning and was due tomorrow evening, for example, the Available filter would hide it, even though it's due soon...
