Follow the leader no create WP

Hello

I am trying to get two rovers to follow each other. I set Follow the leader mode. I tell it which one is the leader and hit start. The Leader generates a WP and the slave goes to that point. But even though the leader is moving it is not generating WP. It only generates the first one and then stops generating. What makes that the slave stays in the first WP and is not fulfilling the function.

What can I do?
