I think that's because <textarea/>s are akin to <pre/>s. Your template
has a newline, three spaces, a newline, and another space in addition
to the data produced by the <?php ?> snippet.

Another note, you're forgetting to escape the data you're pulling from
the database. The template should probably look like:

<div class="formLabel">Teams</div><div class="formElement">
 <textarea rows="2" cols="30" name="event_title" id="event_title_game"><?php echo htmlentities(empty($event_title) ? "H: \n    A: \n" : $event_title); ?></textarea>
</div>
