Hi,
Please provide a screenshot of your "cash" plugin configuration.
Even if you configured the default order status, it can be overriden by the payment method.
Otherwise, the goal of these manual payment methods is to let the administrator validate manually the order to confirm it.
If your goal is to give the points when the order is created, the best will be to change the configuration of the point system in order to give points when the order is created.
