your access to the switch is restricted, sometimes the vendor blocks access to certain load in order to control mistakes, since you can't even enable or disable a set without access to 32 i would look into that, when you disu from 20 you are in load 32 by default.. if you own your equiptment, i would get those limits removed.. they can only be modified by someone with level 2 password
