Hi Jannis! Thanks for spotting this! This was a mistake in 0.3.8 where we originally put rmsd and kabsch-rmsd as an oracle and then later decided to move it to be an evaluator. Now it has been fixed. You can use the source version for now, and we will update 0.3.9 sometimes this week to fix this important bug!
