Date Widget Reservation problem: blackout dates

Dear,

Along with greeting, I need your help to know what is the reason that in various occasions to open the form: https://form.jotformz.com/52354269176663, the widget Date Reservation presents its blackout dates. That is, it is impossible to select them, having to remove the widget and replace new one. Is it because you could be having this problem ?, I remain attentive to your comments, thank you very much.

Note: If review is now in good condition, as was removed and re-integrate form

Regards.

Blacked out dates means that someone already reserved the date. If you want to free up the dates again, we can reset the widget for you. Or, you can remove the widget and add it again. Note that when removing the current widget, that will also delete the corresponding submission in it. 

Thanks
