about crack in JCFpm

I use JCFpm to model rock， I get the crack_.txt.
In website:
https://yade-dev.gitlab.io/trunk/yade.wrapper.html#yade.wrapper.Law2_ScGeom_JCFpmPhys_JointedCohesiveFrictionalPM.recordCracks'

it says that the type (1 means shear break, while 0 corresponds to tensile break), However, in the crack_.txt, like below:

I would like to inquire what type does the '2' means?
Thanks!
