What happened to AxisLabelTemplate on CursorModifer?

Hi folks,

I have this code in an old app:

                            <s:CursorModifier x:Name="MainCursor" ShowAxisLabels="True" ShowTooltip="False"
                                            ReceiveHandledEvents="True" LineOverlayStyle="{x:Null}">
                            <s:CursorModifier.AxisLabelTemplate>
                                <!-- This empty template hides Themes cursor labels -->
                                <ControlTemplate TargetType="s:TemplatableControl" />
                            </s:CursorModifier.AxisLabelTemplate>
                        </s:CursorModifier>

This used to work. But unfortunately, this produces the following error after upgrading (I’m not on WPF v8):
Property ‘AxisLabelTemplate’ does not support values of type ‘ControlTemplate’.

I need this feature because I want to display data from the CursorModifier in a corner of my plot, but not in the built-in axis labels. Setting ShowAxisLabels to False evidently prevents the data from being generated, so I need ShowAxisLabels to be True. The empty AxisLabelTemplate above worked to hide the axis labels, but not this code produces the error above. What can I do?
