Layout breaks with columns order set in mobile

Hi there,

so we face a strange issue:
We created a reusable block, which contains a container with some texts and pictures. We use this reusable block as a sidebar on different pages.

The reusable block is displayed in a column on every page inside a 2-column-row layout. In mobile view, we want to display the column with the reusable block on some pages at second position, which we do in the columns order and width menu. In the editor everything works fine.

As soon as we look on the actual website, we notice that the reusable block completely falls apart and looses all its styling. And this affects every page, the block is inserted, even though we only changed the order on one single page.

Because the site is not online yet, I haven’t got a link for you. Any tips or explanations regarding this issue is much appreciated! Thanks in advance!
