Kicad crashes when routing differential via

Description

I have already routed differential pairs. I changed the dimensions of the differential traces and want to route them new. There are some parts of the old trace left. Every time when I confirm one segment, the dimensions go back to the old default (the default values have been deleted in the defaults list). When I try to make vias without having changed the dimensions to the current one, the application freezes and crashes.
