Workflow status does not get marked as completed even after approvals are done

We have a SharePoint Approval Workflow which is getting paused after the Approval is done . Below are the steps our workflow is following :-

1. A new item is added to the list.
2. The workflow is started manually.
3. Approvers approve the item.
4. The Content Approval status is updated( For some of the items) OR The workflow gets paused and no status change

Also workflow is paused and can be seen in running workflow i.e. Workflow completed event doesnt get fired even though Approval is done , How to mark worflow status as completed and remove the paused workflow from running workfloww list in worflow history.
