The DL button is designed to appear only for data uploaded by the Account currently logged in.
There is a possibility that the account you used for uploading and the account you are logged in with are different due to the use of the Log in function of the SNS account.
Please click on the user name in the upper right corner of the screen to go to the page where you can view the data of the account you are currently logged in to, or log in again with the appropriate account to check the data.
