Welcome!
The referral system is in line for an upgrade to be more elastic and easy to understand but as it is now, it is working correctly.
If you want to get the same link you got the first time you filled the form, just fill it again using the same "personal profit wallet" you entered
the first time. And in the box that opens it will show the same referral link.
Each ref link gets generated for unique members wallet, so there cannot be two links for the same wallet.
You can email support@bitcoine.global
Support will check your referral case and possibly will find what happened.

Thank you for your support and payment proof posting.
