JUNK EMAIL ISN'T WORKING

I recently had to add Office 365 again.  Now my Junk Mail isn't working.  I have quite a few in the junk mail folder, but Junk mail isn't blocking them.  I'm using Windows 10 with a new 365 set of applications.  Is there an update I'm missing.  The settings for Junk Mail seem to be fine. 

Thanks for your help.  Junk is pilling up....
