@ederosia You will probably have figured out a solution by now, but for anyone who might come across this: when the "ProtectSelectionIds" property is not there, you can add it manually in the .qsf file, right after "NewScoring" and "SurveyName". You can use any text editor to do this. Then you can save the file and import it in a new survey, and the Edit Multiple option will be there.
