Another blue dot question

I'm setting up a Monster of the Week game using the Marketplace asset MOTW Mystery Collection #3. On the journal tab, I see that everything--including each of the individual mysteries--has a blue dot next to it. Doesn't that mean I'm sharing them with all players? Not that I've invited any players yet, but when I do, I don't want them to be able to see everything...particularly those mysteries I don't intend to use.

The dots do indicate who has access to the journal entry.  Blue dots represent the 'all' marker.  You can verify that by opening the journal entry (handout or character) and clicking edit, then look in the "In Player's Journals" field.

Thanks for the quick reply! From the edit page I was able to delete the "All Players" flag.
