[Recreator Required] Kantu script running very fast

I saved a script as .html and tried to launch it, but it run so fast.
Usually it has 2sec for a step. I set the speed " Command Interval=Slow (2s delay)" in the settings and added a line “store | SLOW | !replayspeed” on the top, but it dosen’t work.

Strange => Can you add a screencast of the macro running?
