Will I get rescinded? Please help!

I’ve been admitted to UCLA as a transfer for the Fall of 2017. I realized when I got my admission that I reported that I was planning to take a dance class in the spring which I ended up having to drop because it required a joint course (before the app/drop deadline at my school so it won’t even be a “W”). I am an American Literature and Culture major and this class wasn’t needed for anything (I was just trying to take it for fun). I still will have over 60 semester units and will be completing my major prep and IGETC. I called the office of admissions and they said I still have to report the change and won’t get a response back until the end of the month. WHAT?! Would they rescind me for a class that was just intended to be for fun?! Help!!
