What's the issue?

Unable to redirect to the current date/month after clearing the selected date by tapping on the clear option in AMP project. After clearing the selected dates when tapping on the input field the datepicker doesn't open in the current month rather than it opens the previous selected month.
Here I am using the Lightbox date picker.

Please help me to solve the issue.....................
