If a list:<type> field has an IS_IN_SET or IS_IN_DB validator, by default it will get the MultipleOptionsWidget -- otherwise it will get the ListWidget. By default, list:reference fields get an IS_IN_DB validator, which is why you see the MultipleOptionsWidget by default for those fields (list:integer and list:string fields don't get any default validators, so they get the ListWidget by default). If you want to use the ListWidget, you either have to set requires=None for the list:reference field or explicitly set widget=SQLFORM.widgets.list.widget. However, you'll then have to enter record IDs into the list widget fields, which is probably not what you want to do.
