Problem renewing driver's license after green card approval?

[jessdexfit]

I had my interview in October 2018 and was approved on the spot. I received my green card and approval notice in the mail in January 2019. My driver's license is soon to expire, and when I went to my local DMV they were unable to renew my license due to my green card application showing as "pending" in their system. I contacted USCIS but all they could tell me was that their system shows my green card application as approved. The DMV gave me a temporary 60 day permit to drive, but I still have no solution or reason as to why their system doesn't reflect my green card approval. Please, any suggestions or advice to navigate this issue is appreciated!
