"Save" does not get rid of asterisk in filename in Multitrack (yet saves the file) - Audition CC 2018

Just yesterday I was working on a newly created multitrack session in Audition CC 2018. Of course, after you make some changes to the file the filename displayed has an asterisk at the end of the filename, showing that you need to save it (before closing or whatever). When I save the file, it doesn't get rid of the asterisk so I thought it was not saving. Then I restarted my machine, a reliable iMac 27" running with El Capitan 10.11.6, and I opened the file and saw that my changes were indeed saved. This seems to me to be a bug but I don't see any Adobe update available. Is this an anomaly or what?
