Registration form issues

Hello,

I have encountered two issues related to the registration form.

Firstly, when I move to the second screen of the registration form, then click Previous button and move to the first screen, Reconfirm Password and Birthday fields are reset and I have to enter them again. The problem with Birthday field disappeared when I changed the Calendar mode to 3-field combination, but you might want to fix it anyway.

My second problem is with the registration form customisation screen. It seems that I can customise one field only. To give an example, I switched off the calendar view in Birthday field and clicked Save; confirmed that the view had changed on the registration form.

Then I changed Address field - made Address Line 1 optional, - and reloaded the registration form. The address line 1 appeared optional, but the birthday date returned to Calendar view.

Again, in the backend, switched off the calendar view and reloaded the registration form in the front end - Calendar view was gone, but the Address line 1 was mandatory again.

Please help me to resolve these issues.

Regards,
Vlad
