Dear Tommi, did you check whether you collected any reflections at all that should be absent for the second screw axis? If there are non - which could easily happen with low resolution, incomplete data - pointless and XDS might be conservative and not estimate the likelihood for the second screw-axis.
MR, however, will pick up the space group with all data, and thus be able to tell between P2212 and P22121 whether or not you recorded reflections that are expected to be absent.
