That's too long to direct us toward, no matter where you put it.

Your task, then, is to construct a *much* smaller and simpler example
that still demonstrates the behaviour you want explained.

Once you have that, one of two things will be true:

* It will be small and clear enough that we can discuss it here
  usefully. Or

* You will have understood the problem well enough to solve it yourself.

Please, construct a Short, Self-Contained, Complete Example
<URL:http://sscce.org/> of code that exhibits the behaviour.
