PyroCMS Pagination shows Questionmark in link

PyroCMS Pagination shows Questionmark in link

Im creating a module with pagination, when I use the create_pagination()
helper I am getting a question mark in the links.
<a href="http://site.com/mymodule/page/?">1</a>
<a href="http://site.com/mymodule/page/2?">2</a>
The code Im passing in the controller is;
$total_items = $this->mymodel_m->count_by($filter);
$limit = 6;
$data->pagination = create_pagination('mymodule/page/', $total_items,
$limit, 3 );
The second problem Im getting is that I expect the #2 link to display and
offset of 6 not 2
