Hero frame slide change

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)
