Change in Visual editor is not pulled into the Layout Builder

Hi,

I have enabled the debug mode for layout builder. Now when I create a new text block in Layout Builder the shortcode appears in the visual editor.

But if I change the text in Visual editor and switch to the Layout editor the text does not show up.

1. How it appears first after creating text block and viewing in visual editor
[av_textblock]

[/av_textblock]

2. Changing text in visual editor
[av_textblock]
mytext
[/av_textblock]

3. The shortcode still remains the same in layout builder and does not recognize the newly added text
[av_textblock]

[/av_textblock]

Please can you look into this and provide a solution. Thanks.
