DLE 11.2 - BBCode editor, full news missing?

Question

DLE

Good afternoon, when creating content for an article in the BBCode editor, it looks like this:

<div class="zag"><b>Содержание статьи:</b><ol><li><a href="#zag1">Заголовок1</a></li><li><a href="#zag2">Заголовок2</a></li><li><a href="#zag3">Заголовок3</a></li></ol></div>

the full news disappears in the editing section, there is a text on the site, when editing it is empty, you can edit the news only in the visual editor, tell me what could be the problem?
