WPF Datepicker Day of week issue

Question

I am having an issue in WPF with C#, I am trying to use a datepicker with a little issue. When I use it on the main usercontrol it displays no problem, when I try and display it on a linked in user control the days of the week are blacked out. <comlb:LogBookSearch /> Datepicker with days of week blacked out

I have changed this to a calendar and get the same result, I have changed numerous settings including start day of week. I have tried deleting and adding a new datepicker with no extra code - always the same result. I have tried styles but cannot find anything for daysofweek with using a custom control. Any help is appreciated

Sorry When I seen the picture zoomed I realized the issue. I have an open textblock style on this page that has a dark background and a green border when I commented this out - all worked.
