Button state issues (Bug?) - Storyline

Hi Everyone - 

I've been developing a course this week in Storyline 360 and have ran into an issue where the buttons are not retaining their states (particularly visited).  The only modifications I have made to the pre-packaged buttons are the colors.  This has not been a common issue (I've worked on dozens of courses in AS 360) at all - I figured I was just tired or whatever.  Went back the next day, built the slide from scratch and had the same issues.  I decided to use a dial instead. No biggie - figured it was just user error.

However, I am reviewing a course developed (in Storyline 360) by one of my colleagues today in Articulate Review and am noticing the identical problem (again, the only mods to the buttons were the colors.)  We've both run any updates, did our restarts, etc.  

Has anyone else noticed this in the last few weeks?  Is this a known bug?
