my.myob administrator name changes

I am in my.myob manage online access, online administrators.

I am:  first name surname (my email address ) with my role as 'owner'.

The director is also my first name my surname  (his email address) with his role as administrator.

I need to change his name from mine to his.

I  removed access and re invited with the correct details but it defaulted back to my name again??

Please help, i need his name to show correctly in order to set up to pay super from MYOB as he is signatory on the account.

TIA.
