UCSD Supplemental Questionnaire?

For the supplemental, it says at the top to “not refer [UCSD Adcoms] back to information already presented in your original application or personal insight questions.”

However, it later asks for any community-based organizations I am involved with (if any) and include the academic grade level when I was involved.

So, would I leave this part blank since I already included all the organizations i was involved with in my original UC application? It feels odd and bad to leave this part empty.
