无法显示网格/列表选项

Question

 <p-dataView #dv
                    *ngIf="!isLoadingGrid"
                    layout="grid"

                            <button type="button" pButton icon="fa fa-refresh"></button>
                        </ng-template> -->
        </p-dataView>

我的选择网格/列表选项不再显示，我不知道为什么。我使用与网站相同的布局，并且已经工作了几个月，然后突然停止了

您可以看到p-dataViewLayoutOptions仍然存在。任何想法让它像这样
