There are session IDs in my Top Session Finder not found in my Session Browser. (4280129)

I went to Database | Monitor | Top Session Finder. In the Pie Chart, I noticed a session which took up the most resource. I want to look that up in the Session Browser but I cannot find that Session ID.

I also tried going to the Dataset tab, choosing the session, I right-click and selected 'Find Selected Session in the Session Browser,' but it still does not show me the session ID in the Session Browser.

The reason why some session IDs in the Top Session Finder does not show up in the Session Browser is because of a filter setting in Session Browser. In the Session Browser look for a Funnel icon. By default it is in red because the filter "Exclude Null and SYSTEM OS Users" is set. Go to the drop down menu and unselect it. You should be able to see all the sessions now.
