Why is my database missing?

A few days ago I added a new database (called ProductOptions). The list below shows my databases I can see in the Dev mode Editor. However ProductOptions is missing from the Dashboard’s Content Manager’s list.

Can anyone tell me why?

Problem solved! I fell upon the answer when I published the site and observed the Site Event logs. The reason my new database did not show up in Content Manager is that the database permission was set to Private. While I don’t know why permission should prevent the Content Manager from view of my own site content, I know that I built the database using Site Content permission. Since no one else has access to my site, I can only conclude something behind the scenes in Wix must have changed it.
