I have the activity stream on my dashboard. It only display confluence updates, I don't have the ability to select which application I want to see activity for.
I saw someone else had a similar issue https://community.atlassian.com/t5/Jira-questions/Activity-stream-gadget-shows-only-changes-in-the-Confluence/qaq-p/670575
However my issue has not resolved itself.
Click on Add a Filter viewable under the Filters section in your snapshot. That should bring JIRA and Confluence options up. Choose JIRA. You should be all set.
