Hi @tongcongtuan and welcome to the community!

Are you using a dark theme for the learning section of your screen? If so, that could be the problem. I just helped someone else with a similar problem in this post in a different mission.

Let me know if this is/is not the case for you. If it is not, please include a screenshot so that we can “not see” what you “do not see.” :laughing:

@mathmike314 i changed from dark theme to light theme as you advised and it’s solved the problem.
Thank you very much
