The feret diameter cannot be calculated

Dear all,
I had trouble loading Labelmap Statistics from the Segment Statistics module.
I tried all the plugin parameters and noticed that the Feret diameter mm is the only one that does not work.
I wonder if this had anything to do with the fact that I could not download ShapeVariationAnalyzer for the current version of the slicer I am using.
Does anyone else have this kind of problem?
Any advice on how to solve this problem?
