I confirmed this with 5.1.4 but I believe it has already been fixed in the 5.1 branch because I cannot duplicate it there. Would you please install the latest 5.1 build from https://kicad-downloads.s3.cern.ch/index.html?prefix=windows/testing/5.1/ and see if the problem has been resolved. This will be released in the upcoming 5.1.5 stable release.
