Small bug in Directive Snippets form

The colon there seems to be missing something? It's visible when selecting Apache or nginx. Relevant code in /usr/local/ispconfig/interface/admin/templates/directive_snippets_edit.htm:

<tmpl_if name='is_master'></tmpl_else>
    <div class="form-group php">
        <label class="col-sm-3 control-label">{tmpl_var name='required_php_snippets_txt'}</label>
        <div class="col-sm-9">
            {tmpl_var name='required_php_snippets'}
        </div>
    </div>
</tmpl_if>

Not sure what this is for.
