You’re absolutely right – apologies for the inconvenience.
We’ve logged this as something that is in need of attention. In the short term, though, as described in another thread where we were looking at a different situation, please review the Themer’s Guide and then override the wootickets/tickets.php template. Locate this line within it (line 46, approximately):
echo "<td width='75' class='woocommerce'>";
In your theme override, change this to:
echo "<td width='150' class='woocommerce'>";
Does that help?
