You say you're showing your Available actions in your Contexts list, but in your Projects list you're probably showing all of your Remaining actions. Do the rest of your actions show up if you switch Contexts to showing all of your Remaining actions rather than just the Available ones?

Remaining actions include any actions which haven't been completed. Available actions only include actions you can do right now. Actions are considered unavailable or "blocked" if they can't be done right now, i.e. if they're not first in a sequential project, or haven't reached their start date, or are assigned to an inactive project or context, etc.

I just realized that projects are created sequential by default, and perhaps it would be less confusing if they were parallel. You can edit this setting on individual projects, and you can change the default setting for new projects in Data Preferences. We'll consider making parallel the default for future releases.
