Hello Richard,
You are referring to the pop-up message about the layout change that you see after you log in to the website... right? In that case, you must have missed the statement below the screenshot, which reads "PMI is using these new types in the current CAPM exam and will start using them for PMP and possibly PMI-ACP starting next year."
In other words, we will NOT be using these new question types in the current PMP simulator.
