Problem with Layout Grid

Hi,

I just upgraded to the latest version and I have the following issues:

1. When I add columns into my layout grid on my default page, it doesn't add to the other breakpoint pages

2. When I click on the page property, I cant see the miscellaneous tab.

3. Also, the alignment of the breakpoint 320 is out off alignment after the update.

Are there any known issues with the new update?

Any help will be apprecited.

I didn't find the right solution from the Internet.
