[msd]

im having problems with SfListView inside SfTabView on android

it works fine on UWP

the problem occurs only when binding data to the listview

it loads fine on the page

but when binding data Im getting "cannot convert "header" into system.double"

public ObservableCollection<FavoritesList> BkmList { get; set; }
        public BookmarksVM()
        {
            try
            {
                BkmList = new ObservableCollection<FavoritesList>(bookmarksDb.FavoritesList.ToList());
            }
            catch (Exception ex)
            {
                Debug.WriteLine(ex.Message);

            }
        }
