I reported this issue to NAB a few days ago. Below is a part of their response to me:
"We are not aware of any chart-related or market-data related issues on the 30/03/2020. I have just checked this now for CCP and a couple other stocks and the data looks to be updating correctly up to the minute. Are you able to please confirm if you are still experiencing this issue?"
I will be responding to their e-mail along with a few screenshots as proof.
