pagination is incorrect when switch between breakpoints

https://codesandbox.io/s/swiper-centered-auto-forked-40ei1k?file=/index.html

I have breakpoints at 320,768,1024
where slidePerView:"auto" and slidesPerGroup: 1 for 320 & 768
while slidesPerView: 4 and slidesPerGroup: 4 for 1024.

when it's first loaded, pagination is correct. For example, first load at 1024, pagination has 2 bullets.
after switch to 768, it got 8 bullets. but when switch back to 1024, it still has 8 not 2.

is there a solution to this?
