Activity streams are entirely managed in CB Activity > Streams > Activity (or "Activity Streams" button in CB > Plugin Management). Comment streams are entirely managed in CB Activity > Streams > Comments (or "Comment Streams" button in CB > Plugin Management).

I know this is different from before, but those 2 locations are all you need to really be concerned about for configuring streams. So in your case edit your comment streams are turn off the connected access check and you're done.

And, I have "Module 112" under CB Activity: Activity Streams - this module does not exist in the module management. I'm a little confused about that.

You have a Joomla module with an id of 112 that used to be a CB Activity module displaying an activity stream. So it migrated that module to a stored stream. It's possible you deleted that module, but never cleared the trashed modules so it's still in the database in which case it still needed to be migrated in the event you removed it from trashed status.
