Datepicker and date entry

When I use Datepicker to input dates, if I choose a calendar to pick a date then it works with no issue but if I try to enter a date I have a funny effect. Prompt is less than minimal and labels that should be moved and resized to the upper left corner sit inside the entry field. I tried the same setup in your examples and datepicker works as it should but none of my input works as it should. No specific CSS for the input control.

What may I have done wrong?
code:

            <RadzenFormField Text="Od datuma" Variant="Variant.Filled">
                  <ChildContent>
                    <RadzenDatePicker DateFormat="dd.MM.yyyy" style="display: block; width: 100%; height: 60px" @bind-Value="@bRRMSK.DATEND" Name="DATEND" Culture="@Usr.culture"/>
              </ChildContent>
            </RadzenFormField>

Use your browser dev tools element inspector to check what classes are applied and from where they are coming.

Classes that apply to non selected field are
rz-form-field rz-variant-filled rz-floating-label

and when field is selected then it reads
rz-form-field rz-variant-filled rz-floating-label rz-state-focused

all other fields work as they suppose to, moving the prompt to the upper left corner of the field border.
