Grid Column expands when Label break line

Greetings everyone, I'm having a problem when my Label binded with the text "displayString" inside the listview stacklayout is too large and breaks the line, expanding the column it belongs, its shown in the image below:

Here is the code of the ListView, have anyone faced this problem before?

<ListView
                x:Name="MyListView"
                Margin="5,0,0,0"
                CachingStrategy="RecycleElement"
                HasUnevenRows="True"
                IsGroupingEnabled="false"
                ItemsSource="{Binding DevicesList, Mode=TwoWay}"
                RowHeight="60">
                <ListView.Behaviors>
                    <local1:ListViewTappedItemBehavior Command="{Binding DeviceTappedCommand}" Converter="{StaticResource SelectedItemConverter}" />
                </ListView.Behaviors>
                <ListView.ItemTemplate>
                    <DataTemplate>
                        <ViewCell>
                            <!--<ViewCell.ContextActions>
                                <MenuItem
                                    Command="{Binding Path=BindingContext.ShareDeviceCommand, Source={x:Reference Name=MyListView}}"
                                    CommandParameter="{Binding .}"
                                    Text="Compartilhar" />
                                <MenuItem
