Hello. I made a three-column menu a long time ago using a mega-menu (https://b.radikal.ru/b19/2101/45/7470e6799461.jpg). Now there is a need to create another menu (https://d.radikal.ru/d07/2101/3d/bc59ab0a3bbd.jpg), I click manage layouts, select 3 columns (https://d.radikal.ru/d38/2101/f1/24dd4f0f80dc.jpg), then I press reset, then everything is reset as in https://c.radikal.ru/c29/2101/9e/18557eaffcc9.jpg Why can't I make another column menu? I tried it according to the instructions in the documentation section and in different ways. The result is always the same. The menu after the reset button turns into 1 column.
