I just notice I can't create new hub string variables. I am still on version 188.8.131.52, version 154 doesn't mention that and seems a pretty small change. I don't want to update right now as I don't like to do that if I am not home.
I can create all other types but when I try a string after I enter the default value it just shows the variable name and the type select drop down menu.
Only way to get back to normal screen is to select no selection for type and then cancel.
