The Word template you're using doesn't support a preview facility. However, a Moodle plug-in I developed a few years ago (cf. https://moodle.org/plugins/view.php?plugin=qformat_wordtable) does support per-question previews, but using a different, table-based, Word template, and working only on Moodle 1.9. If you run Moodle 2.x, you could preview the questions on my test Moodle 1.9 server, though.
