Initially when splitting a bill the names shown are the names in your phone contacts. After searching the names change to the name that the user used to set up their account.
Also an issue when creating a Shared Tab and adding people to an existing Shared Tab.
Details to reproduce:
Select “Split this bill” on a transaction ==> note the names shown are the names in your phone contacts ==> search for a contact. Only the Monzo account set up names show using the search.
NB: sometimes you have to search then cancel the search for the names to change them from phone contact names to Monzo account set up names.

This issue seems similar to the issue in the Payments tab described here:
