Posts Carousel doesn't work anymore

Hi there,

after update to WP Version 5 the posts carousel is not being displayed anymore. I deleted it, updated the page, insert it again, updated the page, but still it doesn’t come up anymore.

Any help?

PS: I have a multi language page and in English page its working and in German page to doesn’t. I use Polylang in case this is an important info.

Kind regards
Leon
