If you are using new bolting you could try adjusting the EXTRA length in the SBOLT to bring the calculation back to what you need.
It may take a few tries but try reducing the extra length by a small amount eg 0.2mm and re run the iso.
If it works then OK, if not adjust by another 0.2mm and repeat
Make sure you check that the items which are currently correct are not affected.
When I first tested New Bolting I had to use this method in order to get bolt lengths to match ASME B16.5
