You'll just need to click the button again this time, it'll pop up a keychain window, check the "don't ask me again for this type of transaction" or whatever keychain gives as a checkbox option there, else you're going to need to accept click every transaction. Then it'll start creating the custom.json ops one per block with multiple movies in one but with your count it'll still require about ~67 transactions so you'll just let it load fully.

Feel free to test it now in your profile page!
