I select external display and select "show all tracers". Works for that session, when i turn off and come back in another session it only shows last tracer. When I look at option selected it still says "show all tracers". I can change option and the new option (example show last 5) and that will work for current session but next time I play it goes back to only showing one tracer even though the "show last 5" is still selected. Seems like a software bug.
