Player switching color scheme

Hi Heroes,

I have my player sent to light color scheme, modern player.  I am using this for many modules within a learning curriculum.  The first 7 modules worked fine, the player maintained it's setting.  However, about 10 days ago, something happened and every time I open a project, it switches the player to dark color scheme.  

Any suggestions on how to preserve the player?  I always select OK after I set my player setting.
