Not sure if I have the exact same issue but seems related. On 15.3.3530.
I found recent update notes saying there were changes to the menu icon for scripts, but it seems like there have been more changes to the menu structure. I get the button to enable/disable haptics on the center menu during a video, but the entire Haptics menu that should be on the expanded menu (RHS of screen) is missing. It's still detecting scripts and playing them, but seems to be at random (i.e. one of the scripts I have stored locally, odds are is for a different scene). I have no ability to check which script has been selected or change the script.
