unexpected zone for localization tools of an article

Hi, it’s a week or so that when editing articles, trough the control panel, tools for localizing the article are un an unexpected panel (the one whose class = “interface-navigable-region interface-interface-skeleton__sidebar”), i. e. in the right sidear, instead of the wide central zone where to edit the article (below which custom fields have remained).

I deactivated all plugins (except for Travaler’s map). Then I downgraded the wersion of WordPress : no change. I also tried to change the theme : no success.

In this situation, in order to localize an article, I have to open the inspector, modify the width of the pane, and then I can localize and set the mark. I’ts rather tedious! Any idea of how I can come back to how it should be (i. e. the tools for localization situated below the article in edit mode) ?

Thank you in advance !
