Swiper's broadcast picture cannot be dragged to the third picture in angular 5.

sliders in the

carousel chart is uncertain. The data is retrieved from the api API, but there is a delay in data retrieval. I use setTimeout to simulate calling api , and then use setTimeout to update the swiper instance.
problem: the broadcast picture can not be dragged normally, so it can only be dragged to the second one, and then it won"t work. How can I solve this problem?
