Clients set Default Shipping method but not reflecting a frontend

Hi,

Can you plz tell me why customers always "see use address same as billing" checked and they dont see their default set shipping address automatically selected, plz let me know how to fix this, since i tried to recode some part but that also does not work,

Thank you,

there was some server issue, so you may not have been able to access website, but its working at the moment,

still here are the screenshots..

in this screenshot, you see i have set different shipping address as default, prntscr.com/pmoo5q

but when login to frontend, and going forward to checkout, it is defaulting to "Use same as billing address" with checked, which i do not want, people complaining about it, even if they set different shipping address, they have to uncheck everytime the checkbox you see in screenshot attached and select shipping address.

So need to make so that if there is default shipping address set by people, then check box should not be checked and default shipping address should be automatically selected.

let me know if that can be done,

Thank you.
