Scrolling Issue

I have 2 rows. When scrolling I want both of them to move down at the same time, but what happens is that the top row stays static whiles the bottom one (which is a CollectionView, if that helps) scrolls down. The top row only scrolls down after getting to about the middle section of the list. I would like to resolve this i.e. I would like everything to scroll down at the same time.

what I'm experiencing

XAML Code

<ScrollView Grid.Row="1">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="Auto"/>
                    <RowDefinition Height="2"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>

                    <!--My Doctors-->
                    <Grid Grid.Row="0"
                          ColumnSpacing="0"

                        <CollectionView ItemsSource="{Binding MyDoctors}"
                                        HeightRequest="90">
