Ringcentral - Azure Entra ID attribute not right

We have set up our SCIM link to Entra ID and we can provision users. The issue is that when users are being provisioned, their name on RC is not correct.

DisplayName (Entra ID) - Test User

name.giveName (RC) - Test User User

I cannot see why the DisplayName is being pulled through as having an additional surname. The displayName in Entra is ‘Test User’

The attribute for name.giveName is set by the attributes in the Azure app. 

Has anyone else had this issue?
