New one column template for article

Hi!

When change ArticleTemplate.Default.cshtml   “Layout = "_ColumnsOne" “ a get this error.
The following sections have been defined but have not been rendered by the page at '/Themes/Bootsclean/Views/Shared/_ColumnsOne.cshtml': 'left'. To ignore an unrendered section call IgnoreSection("sectionName").

A whant to use colmne one is it possible?

Ver 4.1

Remove this block of code

@section left {
    @await Component.InvokeAsync("ArticleNavigation", new { currentGroupId = 0, currentArticleId = Model.Id })
}
