I also had this problem and got rid of it by removing the "<div class="clear">" from the css.

It was only on a couple of installations (not others) and I assume it was a conflict with the template css.

You can test by removing it and using line breaks instead as in...

Original:

<div style="margin-left:15px;">
<div style="float:left;margin-top:5px;width:100px;">###FIELDNAME###</div>
<div style="float:left;margin-top:5px;">###THEFIELD###</div>
<div style="float:left;margin-top:5px;">###ASTERISK###</div>
</div>
<div class="clear"></div>

Changed:

<div style="margin-left:15px;">
<div style="float:left;margin-top:5px;width:100px;">###FIELDNAME###</div>
<div style="float:left;margin-top:5px;">###THEFIELD###</div>
<div style="float:left;margin-top:5px;">###ASTERISK###</div>
</div>
<br/><br/>

You will probably have to add the <br /><br /> after every field...
