Did the new update change the "hide all" option? Can't display just one flight path

Prior to the recent update, I enabled the "hide all" options for my flight paths, because I only wanted to display one flight path at a time.  Upon a new swing, I wanted the prior flight path to disappear.  This worked just fine until the new update.

Now, if I enable the "hide all" option, there is NO flight path shown - only the numeric data appears.  If I don't enable "hide all" then I see many flight paths on the screen at once (the older ones are dimmer, though).

How do I get it to show one flight path and only one flight path at a time?
