Hi,
There is an option in the AlphaUserPoint plugin named "Gives Points on statuses".
In this field you have to list all valid statuses. If the order change to a status not listed, points would be removed.
When this field is empty, the plugin would just retrieve the "order confirmed status" from the HikaShop configuration.
My recommendation is (for a classical configuration): confirmed,shipped
