No, it's not a screen error, it's built-in.
It is one of my pains. The work-around is to save settings when softlimit is off. If you want softlimits automatic on then forget the config/general tab, you have to turn it on in M99998.
E.g. my X settings are: home offset -21.0 and softlimit -20.0. If softlimit is on and I press apply, the
home offset will change without any notice! That is the worst choice, because it changes the home offset and I already had broken tool because this.
