Hero frame slide change

Hello,
Does someone know how to ensure that the hero frames change automatically.
When I create it as the first section of the program, it seems to work well. But at a section after some other sections, with the exact same config, it doesn’t scroll automatically, even if I have put the timers for slide change.
Does anyone have any pointers?
Here is the page that I am trying to manipulate (test webpage)
https://test-kt-d8.web.cern.ch
Top of the page-. automatically scrolling.
At the bottom of the page–> doesn’t scroll automatically

Thanks,
Priyanka
