You have a lot of flexibility in deciding how to list Experiences. If an activity covers several categories, choose the one that balances your application best. For example, if you already have other nonmedical cmmunity service, then the one that is about an artistic endeavor would be better placed in the latter category. The name or description of the activity can make clear that more than one category is covered.
You also have the option of splitting out components of an activity and listing them separately. Eg, you tutored kids after school for two years, but then became the organizer of the endeavor for the following year, recruiting and training others, and having control of scheduling and liaison with school officials. This could be done in two spaces, or in one space, with the two date spans/named activity discussed separately, or with the narrative discussing how you started and how the activity evolved.
BTW, one would NEVER list the same activity twice with two different designations and duplicate identical hours.
