I have the same issue using Maya 2019.2.
Is there a way to fix it for Maya 2019.2?
Also, I'm wondering if it is fixed for a newer version of Maya? Maya 2021, for example?
UPD: I just tried to use the following script command and seems like it works properly although the Selection Constraint UI is continuing to show incorrect data.
polySelectConstraint -m 3 -t 0x8000 -l on -lb 0.1 2.00;
