Date Suddenly change when I click on add more - This problem still exists in version

Dear friend

As I mentioned a bug in your previous versions of your module in this link

I tested your new module 2.0 alpha and I found that this problem still exists in your new version.

When I set unlimited cardinal for an instance of date field that it's calendar system is Persian, when I click on add more, all previous date combos suddenly changed and all dates have been set to wrong value.

Please see this link and watch the attached video.

I really hope that you can repair this problem
