Sorry, your right. Try this:
In the Components panel (not Screens) and with the component selected, create a New custom property. I named mine "ResetTrigger". Use the settings in the image below:
For the Component (yours: cmp_Swipe), you now have a property called ResetTrigger, set it to 50.
Then set its OnReset property to "Reset(Slider2)", (or whatever your slider control's name is in the Component).
The Slider control's Default property, I left mine blank.
Finally, back on the Screens panel, in my button's OnSelect, set it to Reset("ComponentName". In your case, probably something like, "cmp_Swipe_1"
Hopefully you understand you could put that Reset() in a string of functions, Maybe even at the end of your OnChange functions.
Let me know if it works
