Pay super , some funds rejecting

I ran my monthly payrun and completed my first pay super for April but some of the employees' super payments did not go through whereas others did so successfully.  I'm receiving this message for these rejected employees  "This Fund can no longer receive contributions using Pay Superannuation.  Please edit the fund from the Superannuation Fund list Window and select a valid Fund Name for it" .  The superfund listed in MYOB has been re-confirmed and entered by each employee into MYOB as correct so not sure why they are rejecting?
