Hi Li-ran.
I’m afraid this is a known bug that is yet to be addressed.
I believe you see a “Pagination should only be used if your posts are the only thing in the content area to prevent duplicate content issues.” note when you set the pagination. It is directly related to this bug.
As this issue is pretty complex, We can’t give an exact date as to when this bug will be fixed.
At the moment, we can only advise to avoid using pagination along with the carousel.
We’re sincerely apologize for any inconveniences this brings.
