Checkout billing address does reflect the saved billing address

Hi,
The checkout billing fields do not reflect the billing address details saved in the user’s my-account.The billing address you save under my-account for the first time will be used for every subsequent checkout done by you even if you remove that address from your account.The updated address is never reflected.
I have tried this on my localhost as well as on 000webhost.
