Translating pages with tabs

Hi,
I am testing WordPress 5.0 and Kadence Blocks in our sandbox environment. Really like Kadence Blocks, nicely complementing the other plugins out there…

I have created a page (“abc”) on our site with 3 (Kadence) tabs. Inside the tabs, I am using a “Post Masonry” Block created with the “Ultimate Addons for Gutenberg” plugin. This works nicely in the original language (EN).

When I translate the page with WPML, the resulting German page only shows the first tab and that tab is very narrow (maybe 5% of the screen width).

I opened the German page in the Block Editor, there, WordPress complains about a broken block. See below for the generated code on the German Page:
