Drag and drop custom button not submitting

i used a custom button for a sequence drag and drop and I have a few failures. See slide 4.4

1. I cannot hover over the button (NOS)= picture 5. It seems like I have to move all items for it to activate. 
2. I wanted to add a custom image inside the feedback layers but there is the white box in the background I cannot get rid of.  (see 3.3 for correct visual)
3. Even with the triggers, i cannot get it to advance to the next slide

Its a mess that I just cant figure out what I did wrong. Any help would be greatly apricated and may keep me out the nut house
