Just for the record to anyone reading this in the future: Same thing happened to me, I created a custom profile and tried to switch to a different custom material profile, this made the profiles: "Dynamic, Standard, and super quality" dissappear. The solution to get them back, was to change back to one of the Cura Default profiles (for material). In my case I changed from "Hydro's custom filament" to "Generic PLA" and I was able to get my print quality profiles back.
