Problem with date

Hi Team,

Currently, I have created a form where the recipient, depending on the choice of the superior dropdown (“Przeprawa wyjazdowa” and “Przeprawa powrotna”), can select a date that is hidden until the value is selected in the parent fields (listed above).

Dropdown 1: “Przeprawa wyjazdowa” -> EN translation = “Outbound Crossing” is required and when selected, additional fields will appear, including data field, which is also required – everything works fine here.

Dropdown 2: “Przeprawa powrotna” -> EN translation = “Return crossing” is not required, but after selecting it, additional fields will appear, including: the data field, which is required in this case – the problem is that if the recipient does not want to select anything in the dropdown, but completes all the previously required fields, the form returns an error anyway: “Form has not been submitted, please see the errors below. ”
After some time I came to the fact that despite the lack of the requirement for the “Return crossing” dropdown, the hidden field data_2 is still required and the form without selecting it does not go any further.

I hope that I have clearly described the problem, I will add that other hidden fields depending on the “Return crossing” dropdown do not return this error despite the requirement and hiding. I tried to delete this data_2 field and insert it again, but it doesn’t do anything.

I am asking for urgent help on the subject.
