Thanks for your interest in ARX!

This is likely not a bug but an expected error message. The hierarchy that you are using for the attribute age either (a) doesn't contain a generalization rule for one of the values appearing in the dataset (example: dataset contains age "99" but the value "99" is not contained in the hierarchy) or, (b) contains an ambiguous rule (example: "[10, 20[" can either be mapped to "[0, 20[" or "[10, 30[").

I hope this helps, Fabian
