Blocks

Hello,

I’m having a problem with the overall display of blocks.

In the page template editor, my default template correctly displays the blocks that will be used by the pages I’ve created (see Page image link).

In the Pages section of the administration, when I want to add content, I can no longer find the Group block as it appears in the page template. It’s replaced by a Content block, and I can’t add a new Group block before or after this block, only within it (see Page Template link).

I’m using the Spectra One theme. When I replace it with Twenty Twenty-Four, the blocks disappear completely.

I’ve also disabled the plugins, but that doesn’t change anything.

Do you have any idea what’s causing the problem?

Thanks.
