Issue adjusting current step within sequence

Hi all, 

I am having an issue with updating the current step within a sequence. I have an app parameter bound to the current step property of my model and I adjust the app parameter through JS when different step buttons are clicked. This works when moving from say Step 2 to Step 4 but it moves the step 3 pieces way away from the home positions they should be in. Any ideas why this may be? I've attached a picture of what I mean with the pieces being way off. 

Thanks in advance
