It appears to my untrained eye that the TextBindMappings for the changeLabel
& lowValueLabel have been switched.
<Label wtkx:id="changeLabel" Form.label="%change" textKey="change"
textBindMapping="$valueMapping" styles="{horizontalAlignment:'right'}"/>
<Label wtkx:id="lowValueLabel" Form.label="%lowValue" textKey="lowValue"
textBindMapping="$changeMapping" styles="{horizontalAlignment:'right'}"/>
