Possible Bug in postbit_signature_end ?

[ARP]

Hello guys,

I try to add some thing under signature using the template hooks in pugins

That's My code :

PHP Code:

$template_hook['postbit_signature_end'] .= '<a href="forum.php">Test</a>'; 


In postbit_display_complete

And After that I see the system duplicate the plugin under the signature.

See picture in attachments, However if I change the hook location to signature_start it's not dupliacte. So is this a Bug ?

Thanks All,
