Registrar Lock on clientdomaindetails.tpl

Greetings from Istanbul,

We are having an issue with that registrar lock/unlock function on clientdomaindetails.tpl

We use a theme and have that lines which are a bit different from what WHMCS refers on the same file.

But even that we can disable registrar lock (we can unlock) but we can not enable registrar lock (we can not lock).

<form method="post" action="{$smarty.server.PHP_SELF}?action=domaindetails" id="formlock">

<input type="hidden" name="id" value="{$domainid}" />

<input type="hidden" name="sub" value="savereglock" />

{if $lockstatus=="locked"}

<p><input type="submit" class="btn btn-danger" value="{$LANG.domainreglockdisable}"

onclick="document.getElementById('formlock').submit();"/></p>

{else}

<p><input type="submit" class="btn btn-success" name="reglock" value="{$LANG.domainreglockenable}" onclick="document.getElementById('formlock').submit();"/></p>

{/if}

</form>

Do you have any ideas please? We tried something but could not solve the problem.
