Issue with certificate renewal for exchange Edge Transport Server

Hello team,

I have come across a very particular problem
I deployed 2 exchange server 2019 with one edge transport server 

When we are renewing the Certificates with  wildcard certificate  on both mailbox server ,and on edge transport server ,it is impossible for me to renew the edge subscription

It says the cerificate is in "doublon" (repetitive) on one of the Exchange servers.I have always been using same certificate on exchange server be it edge or mailbox

I tested a bogus different certificate on mailbox and on edge,only then th e edge sync works

Did anybody come across this issue.

Thanks
