OPA2320: OPA2320AIDGKR - marking issue

Part Number: OPA2320


About P/N# OPA2320AIDGKR , we met issues as below

1. The pin1 format is a fan for our part, while the datasheet shows it should be one dot
2. Space between logo and date code is smaller than what we have received before

(Pic 1 on the left is the part we have doubts, Pic 2 on the right is what we received before )

Could you help solve this problem?                         

Thank you
