The flaw is clicking the OK button or the Sort button while viewing the Variables tab, don't do that because all variables viewable under the Variables tab will be permanently set, instead click the Cancel button or switch to another tab and the variables that are currently viewable under the Variables tab will not be saved. Try the same thing as before, but rather than clicking the OK button, switch to the Remotes tab and then switch back to the Variables tab and your temporary variables will be gone.
