Hi Bert,

This is a known issue for Forms above 10.4. 

• If a required file upload or rich text field is empty and above the top of the window when the submit button is selected, the page does not scroll back to that required field. (170432)

The root cause is that there is a hidden field for file upload, and parsley cannot auto scroll to it since it is hidden.

As workaround, could you try following custom JavaScript code to see whether it solves your case?

$(document).ready(function(){
        $.listen('parsley:form:error', function() {
            var firstErrorField = $('.parsley-error').first();
            if (firstErrorField.attr('type') === 'file') {
              firstErrorField.parent().find('input').focus();
            }
        });
})
