If you are turning left, you must be in the left lane before entering the circle. Just like at a traffic signal. You signal that you are turning left. When you proceed, You will be on the inside of the circle. Drive thru until you reach the exit, keep your lane and exit. No need to cross over lanes. The circle is designed to avoid this. The lanes lead you out without confusion everytime!

If you have to make a full circle, you must be in the left lane. Just like if you were making a u turn at a traffic light. Signal, then make your u turn inside the circle. Signal right to exit. Again, the lane will lead you out without having to cross lanes.

How and why is anyone crossing lanes? Just pretend there is a traffic light at each circle. Am I wrong? Starting to second guess myself.

You are 100% correct as that is the way I understand these RABs are to be navigated. In fact, I just posted exactly what you have said in this post but a bit more concise. We are on the same page.
