Loading Buttons don't show up

I’m using Block-21 in my theme. But when I tell the block to have “infinite Load” or “load more button” the Block header changes in an ugly way.

Seems like there should be some buttons, but they don’t show up.

Some Idea?

Hi, i deactivated all plugis and cleared cache. No Changes. Theme is up to date. I used the Art Creek Demo as a Base and modified it. Maybe that could be something?

Same Problem when i create a new site

I think it hast to do something with the Art-Creek-Demo as a base.
Because i tried the layout in a new wordpress installation with the import/export function of tagdivnewspaper, but i didn’t install art-creek-demo.

Here everythink works fine. So i think the problem might be inside custom-body-class of td-art-creek.

I can really get along without the base of art-creek demo, but unofrtunatly now the nice style, for the blocks (Shadow behind the fotos; Centralized Category, title, date; Next-Buttons on the left sind) is gone. Is there a possibilty to import just the custom-body?

Thanks

Is it possible for you to send me a custom code just as you did here?

Would like to add as custom code the style of the “Traditional Art”-Block and also the dark row style (“Interviews”) where the title changes its colour to white, as seen here: https://ibb.co/dt6md2W

Is that possible?

Thanks.
