Fill does not work after first dataset

Expected Behavior

Just trying to do a simple fill in my line chart. The first dataset works, the the next two do not fill.

Current Behavior

Only the first dataset fills

Environment

<script>
            var config = {

		window.onload = function() {

You maybe could also try setting the datasets at 50% transparency or something like that if you want to see the ones behind
