Core component tab is not working properly in AEM cloud

[Ronnie09]

1. Whenever I add container in dialog i need to save and reopen dialog to author container name initially it comes with no name.

2. Whenever I am adding container, 2 containers are getting added. Dont know why.

Console doesn't log any error, I am using core component version 2.19.0
