We are using version 2016.1.217.40 of the Telerik.Windows.Controls.Input dll and whenever we create a custom style (via copy option in Expression Blend) it breaks the Calendar Panel.
When I say breaks, if you attempt to scroll through the months using the left or right buttons it doesn't refresh the days, i.e. the week numbers stay the same.
If we don't override the style it all works fine. Note, at this point we are not changing anything in the style, we are simply copying it as is.
This did work ok on the 2013.3.1016.40 version.
I have also tried the same on the 2016.3.914.40 version and it also does not work.
Is there anything extra that needs to be done to maintain the functionality when overriding the default styles?
