TYPO3 Core

I use just normal backend layout configuration with two columns: header, content

When I switch in the backend to language Mode and the "header" column is empty, it shows the header column on the bottom of the page. The sorting of the columns is neither dependent on the colpos nor the position inside the backend layout configuration.

The array exists with content elements, when the whole colpos setup is built up, so the columns with content element get sorted first. I wrote a simple patch that resorts the colpos after the original setup from the backend layout.
