Trying to run an a previous class but keeps switching back to a new one (even if you close it)

I'm trying to run a specific class; but, when I do it just reverts to another class that has been previously run; and, until I fix that specific class, I won't be able to ever run the on I am trying to. 

Ex I just wrote a class called MaxClass, then I opened another class called AvgClass; so, when I try to run Maxclass, it just reverts back to running AvgClass every time.  Even if I close AvgClass, and select "Run" MaxClass, it will just open AvgClass back up and run it instead.  I don't have time to go back and fix every little thing on classes I don't care about right now.  What am I doing wrong. 

Any help is much appreciated, new to IntelliJ and fell in love with it immediately!
