Thanks for the quick fix.

Luckily, this bug seems to not have impacted other code and the example notebooks since this function which loads the old example CML data is only used (as far as I can see) in the WAA notebook where not rain rates estimates are calculated from this old example data (only from the new example data) and hence the error in length calculation has not effect.
