Blocksy Landscape After first edit different container sizes

Hello,

I’ve set up a new system and installed Blocksy with the demo page “Landscape” in the Gutenberg version. For example, when I want to edit the homepage, various containers/blocks are displayed in the wrong size directly in the edit. Normally, all edges are bundled at the same height, but not here. See screenshot.

You can see what it should look like on the demo page: https://startersites.io/blocksy/landscape/

Please help, thank you!
