As @Sukanta_Biswas mentioned the studio has been going back to some older levels and making changes. Last week a player wrote here in the community that they made a complete change to a level where you didn't need to clear jellies anymore. She said when you look on the map the colors pertain to the type of level that it is. So if it's a jelly level it shows one color but if it's an ingredient level it's different. I never took note of that. So the studio changed it from a jelly level to something else but didn't change the actual level button.
