Hi Terry
you may want to look in netweb.css for RightJustify and see if the new code is in there. You should see
.RightJustify{text-align: right;}
.RightJustify .nt-flex{justify-content:right;}
if not follow the files back to see why your app folder doesn't have the latest files.
if it does have that there be sure to re-run gzipall.bat, and make sure the new files are deployed to the server.
