Please help: slider error - slider name is not consistent in the timeline and in the trigger panel

Hello, 

I am trying to develop a slider interaction to explain the different effect of debits and credits on different types of accounts. 

So what I want to do is to drag the slider of Credit, hence the coin stack of expenses and revenue would increase and decrease. -- so when I drag the Credit slider upward, the Expense coin stack should decrease (which it does) and the Revenue coin stack should increase -- but it doesn't. 

I checked the triggers and I think everything is correctly set up. 

Only thing I see strange is that the slider is actually slider 1 in the timeline, as well as in the trigger set up window. However, in the actual trigger panel on the right side of the screen, it is marked as Slider 6.  I think that's because I have been playing around a lot and had added and deleted a lot of sliders.

I attached the story file here. 

Can someone please tel me how to fix it?

Thanks a lot!
