TAdvSmoothDatePicker button styling

I am new to the TMS Components, but I have most of them styling correctly through the appstyler, formstyler...

My issue is that the TAdvSmoothDatePicker's drop down arrow button is still battleship gray and I can not figure out how to style it.  Help?  FYI:  The popup date selection dialog is behaving perfectly.  I am using version 2.2.0.0 in Delphi 7 Pro.
