empty date issue when using combo date

[opencubicles]

I am unable to set the combo date input values from non-empty to empty.

http://jsfiddle.net/opencubicles/vu8zLoh3/21/

it's not required input.

Can you be more specific on what your issue is?

When I go to the jsfiddle, I see a value for User DOB and I can change it.

If you try to edit the date and leave the values for all the options as empty for combo-date dropdown and hit save, it will not retain the new empty value.

Pls check the screenshot below
