The required validation worked fine when I tested your form.
However, as suggested by Kiran, please disable the 'Continue Forms Later' option via form Preferences, since it is not compatible with the session based continue later method.
Once you disable that option, please test the form again to make sure that validation issue is completely fixed.
If you need any further assistance, please let us know.
