Adding multiple AND conditions in validation setting in SharePoint Online new form controls showing

I have some text, date, dropdown fields on new form. there I have added formulas with multiple IF AND conditions. when I am filling first two required field and clicking on save button it shown error message which I have added in validation settings but after that when I clicks on date field which is next to three mandatory fields then it auto focus on second required field.

I don't want that autofocus or why it is autofocusing on that field?

Thanks in advance.!!
