Hello @anhthiencao,
I don't have any problem on the demo instance (Chrome or Firefox latest version). Can you confirm the problem is still there? Maybe the demo was overloaded when you tried.
Can you also try with the latest version of Firefox?
Thanks!
Kind regards, Samuel
This problem just happened in a little bit, maybe your connection is fast so you can't see it. You can try it with slow 3G in Chrome browser
