Performance-Graphs-Events

When I click on the Performance-Graphs, the Events previously listed all installs, including Microsoft.  It no longer does that.  It appears that it lists all other installs such as Mozilla Firefox, adobe, etc., but not the Microsoft installs.  Those previously listed (up until about two weeks ago) show the Microsoft installs.  I am not sure if this is intentional, or if updates to Norton did not install properly.  I would appreciate hearing from other users.  I am running Windows 10 and Norton Security version 22.7.0.76
