Issue with cancellation of subscription

Just because it comes from your Apple account, does not in any way mean its specifically for that old subscription.

Other recent purchases? click here ➜ If you see 'apple.com/bill' on your billing statement - Apple Support

If it expired, then there's nothing to cancel, so no no cancel button would be available, and it cannot be charging you.

Where are you seeing the charge for it exactly?

Why do you assume its for this subscription specifically?
