You had it! 
It’s the >> next to these buttons here.
So if you Open up the interaction UI and get the BT started, then PAUSE the simulation (use Play In Editor for ease of use) you can use these buttons to go one step at a time to prevent it from going too fast. It’s very likely that’s what is happening.
The first one is working perfectly, at least. It’s supposed to skip over.
Your decorators are set to 0,1,2,3,4 etc I assume? If so, we need to check why it’s returning false, possibly within the code to set the output?
