AlphaFromTo Effect not working as expected in Drag and Drop

I am using Adobe Captivate 9. I have a drag and drop interaction where once the drag object is dropped on the drop target, the drag object goes from 100% Alpha to 0% Alpha (without clicking a button). I am using an advanced action using Apply Effect > AlphaFromTo.

What happens is that the drag object, when dropped on the drop target, will go from 100% to 0% Alpha, but will then change right back to 100% Alpha. I need the effect to be permanent, so that it will stay at 0% Alpha. I have the Effect Duration set at 0.5 seconds.

Not sure if this is a timing issue, or if this effect is designed only to work once and then go back to it's original state.

How can I get the object to remain at 0% Alpha?
