Thank you for contacting us.
By design, you should be able to select also the dates from the other months when the popup calendar is opened. When you select a date, the popup calendar should be closed and the selected date should be displayed in the text field. However, it seems that we have introduced an issue in the latest release and we will do our best to address it for the Q1 SP2 release.
Please feel free to contact us, if you have additional questions.
