I think the libraries are different somehow. I have the same version of the library, but when i click to export, it behaves differently, mine will try to open a popup whereas the sample online doesn't. I've copied the sample code, but it still behaves differently. on my local version it loads a popup and the filename is always a guid without an extension as well. have attached it
I am including
jquery 3.1.1
<script src="~/Scripts/jquery.easing.1.3.js"></script>
<script src="~/Scripts/ej/web/ej.web.all.min.js"></script>
