Cancel B2

Hi! I’m currently in my J1 visa. Due the COVID, my DS was supposed to expire in June 10, but not I’ll be able to renew 6mo. Otherwise I already applied for my change of status J1-B2 .. Should I cancel my application for B2? After 6mo I’ll need to apply for B2 again as a GAP for my F1 that I’ll also apply at the end of the year. What’s should I do?
