Data picker does not work correctly in subform which is in reports header

[Miroslav]

I have date picker which works correctly in form. When I put that form as subform to reports header calendar shows up but after selecting date on calendar textbox stays blank. Format of textbox is Short Date, Show date picker property is For dates.

See if there is any method associated with the control that cancels the update.
