Xamarin.Forms.CarouselView - missing text in labels

Hey Guys,
I'm new in xamarin.forms and working on my first professional app. I'm using the CarouselView for scrolling between informations like in attached images. At the forward scrolling all informations are complete and all labels getting the expected informations. After back scrolling, the labels losing some informations. I have no idea whats going worng there. No exception or other errors.

Thank you for support in advance

        <carousel:CarouselView ItemsSource="{Binding Searchprofiles}" Grid.Row="2">
            <carousel:CarouselView.ItemTemplate>
                <DataTemplate>

                    <ScrollView>

                        <Grid Padding="10">
                            <Grid.RowDefinitions>
                                <RowDefinition Height="auto" />
                                <RowDefinition Height="auto" />
                                <RowDefinition Height="auto" />
                                <RowDefinition Height="auto" />
                            </Grid.RowDefinitions>

                            <Label Text="{Binding Datum}" TextColor="Gray" FontSize="Micro" HorizontalOptions="EndAndExpand" Grid.Row="0" />

                            <Grid  Grid.Row="1" >
                                <Grid.ColumnDefinitions>

                                </Grid.ColumnDefinitions>
                                <Image Source="..." VerticalOptions="Start" Grid.Column="0"/>

                        </Grid>
