Jump to next slide manunally

Hi everyone,

I have a demand in my Storyline project is that in some slides, I need the user to click "NEXT" maunally to go to the next slide, and some slides can automatically jump to next slide when the timeline ends.

I know it sounds simple, but weired is that I've already delete the trigger "Jump to next slide when the timeline ends", it still triger automatically. Any ideas?
