I saw that it is fixed now in RC0. Great! :w00t:

Though my "old" models, created in CTP3 doesn't get "cured" just by being edited in SSDT CTP4 or by being deployed to a RC0 instance - it still needs your fix to hide the "___Count of Models"-measuregroup in the excelsheet. How do I comment a row in XML? /**/ or -- or something else?
