Well, clearly the H4 is not a CSS definition and the code says its after
<td class"tcat" colspan"6">

<td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>"> <h4>
            <if condition="$childforumbits"> <h4>
            <a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
            </if>

            <a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]</a>
            <if condition="$show['forumdescription']"><div class="smallfont">$forum[description]</div></if>
            <if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
      </h4>  </td>

So the redcoloured tags are the possible placement within your code.
You sure you don't want me to look at it in your ACP?


Can you run the search in all styles?

Edit: After you posted your code, then the only pausible explanation is that you're looking at the wrong style.
If you want to be sure, add ZZZZZZZZZZZZZZZ to $forum[title]. If the title now shows (current title)ZZZZZZZZZZZZZ, then its the same template.

<if condition="!$show['collapsable_forums']">
<tbody>
</if>
    <tr>
        <td class="tcat" colspan="<if condition="$vboptions[showmoderatorcolumn]">6<else />5</if>">
            <if condition="$childforumbits">
            <a style="float:$stylevar[right]" href="#top" onclick="return toggle_collapse('forumbit_$forumid')"><img id="collapseimg_forumbit_$forumid" src="$stylevar[imgdir_button]/collapse_tcat{$collapseimg_forumid}.gif" alt="" border="0" /></a>
            </if>
            <a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]">$forum[title]ZZZZZZZZZZZZZZZZ</a>
            <if condition="$show['forumdescription']"><div class="smallfont">$forum[description]</div></if>
            <if condition="$show['subforums']"><div class="smallfont"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
        </td>
    </tr>
<if condition="!$show['collapsable_forums']">

</if>
<if condition="$childforumbits">
<if condition="!$show['collapsable_forums']">
<tbody id="collapseobj_forumbit_$forumid" style="{$collapseobj_forumid}">

$childforumbits
