1st year ref dilemma! Pick up flag?

[JDLJ]

While you work as a crew, you are responsible for your own actions. If you throw a flag for two forward passes and the WH tells you to pick up your flag because he doesn't know that's illegal you have a problem if the coach asks you why the penalty isn't being enforced.

If you don't tell him he needs to talk to the white hat, what are you going to say? It was the referee's decision and he should be able to stand behind it.
