Why is Anakin addressed as Master in TCW and RotS?
1. RotS the younglings call him master, but you could claim that they're children who don't know any better. Plus them calling him master could just mean that they really look up to him as a mentor.
2. in TCW Anakin is addressed as master by Dooku and a few others. This is less excusable as they should know better.

Could "young master" be Dooku's way of mocking him via dun moch?
Barriss calls him master as well here: https://youtu.be/2tMQyJCKLcw?t=25s
In legends Barriss would've been a jedi knight by this time, rendering the claim that she calls him master due to rank difference as incorrect.
I'm not sure if she would've been a knight by then in canon, but she's not wearing the padawan braid in this scene.
