hide reputation completely in postbit

[seite7]

In postbit I am showing the reputation value. I gave my users the option to hide their reputation but the values are still shown.

<vb:if condition="$show['reputation']">
<span class="postbit_reputation" id="repdisplay_{vb:raw post.postid}_{vb:raw post.userid}">Renommee-Wert: {vb:raw post.reputation}</span>
</vb:if>

It seems the conditional statement (if condition="$show['reputation']") has no effect at all. Anyone knows how to solve that?
It seems the only thing this user option (Hide Reputation) does, is change the actual reputation images to one grey one. But I would want this whole display to disappear. I saw some hints for that for VB3, but not for VB4.
