Saw on NA side people were talking about this, shield SP isn't awarded upon guild leve completion and the JP side also asked about this and they got a response.

Talked to the dev team about how you wont get the shield SP after guild leve completion. They said they will try to fix this at early stage so you can gain the SP for shield.
