WhatsApp Payment : Your phone is linked to more than one account in bank

Just got WhatsApp update and it enabled the payments feature. Out of curiosity, I tried to set up the payments and after checking my phone number, it says your phone number is linked to more than one account in the bank. I've two accounts in the bank and they share my phone number. I want to know if there's a way to select one account and proceed? I'm in no mood to change the phone number on my bank account just to get WhatsApp payments working.

Does anyone have a fix for this?
