The account set-up name of a Monzo contact appears in a Shared Tab instead of the phone contact name.
This can, and has, lead to confusion especially since only the first name is shown in a Shared Tab.
Details to reproduce:
Create a Shared Tab with a Monzo contact whose account set-up name is different from their phone contact name.
