It is completely unnecessary to reset Cura to the defaults, removing all custom profiles.
Just select one of the default qualities, and Cura will ask you if you want to keep any settings that are not stored in a custom profile. Select "Discard changes" and you are back on a default profile with default settings.
There is a guide for this here: https://support.makerbot.com/s/article/1667337567843 😀
