[SOLVED] Automatic number of digits in Discretization interval labels

The automatic number of digits feature is generally very useful, but sometimes doesn't seem to make the right decision.

For example, in the following process, the examples range from 0 to 0.003, but the discretization bins are [-inf-0.0] and [0.0-inf].
