Changed Apple Pass Banner Image but reverting back to old image after 1-2 seconds

Hello all, I am currently trying to update my Apple Pass Banner image and have made the changes. I am seeing some weird behavior where basically I download the pass and add it to Apple Wallet, and when I open Apple Wallet to see the pass, I see the new image for 1-2 seconds, and then it reverts back to the old image. I have went ahead and updated the SHA values in the pass.json as well for the new images but it still seems to be doing it. Does anyone know what might be happening here?
