We run four payrolls. Three have RFBA that require data entry at point of STP Finalisation. Two of those with RFBA worked perfectly, I added the RFBA and then completed the Finalisation. The 3rd one keeps coming up with an error:

I've tried everything over and over, refresh browser, a different person has also logged in and attempted the finalisation with the same result.
Where to from here?
