Cockpit Interaction does not work with LMB

Hello,
I am trying to get a cockpit switch working, and the interaction is just possible with the mouse wheel. It is highlighting the switch yellow when I click with the left mouse button, but no animation is playing, and no input event is called.

here is my xml code:

<?xml version="1.0" encoding="utf-8"?>
<ModelInfo>
     <LODS>
		<LOD minSize="0" ModelFile="PilotInstrumentPanel.gltf"/>
	</LODS>
    <Behaviors>
		<Include ModelBehaviorFile="ASOBO_EX1\InteriorDefs.xml"/>

		<Component ID="CONFIG">
			<Parameters Type="Override">
				<UseParametersFn Name="ASOBO_Configure_Global_Parameters"/>
			</Parameters>
		</Component>
		
		<Component ID="ENGINE">
			<Parameters Type="Override">
				<IE_TYPE>ENGINE</IE_TYPE>
			</Parameters>
			<UseTemplate Name="ASOBO_CT_Switch_Template">
				<IN_BASE_NAME>SWITCH_Starter_R</IN_BASE_NAME>
				<IE_NAME>STARTER</IE_NAME>
				<TOOLTIP_ID>ENGINE_STARTER</TOOLTIP_ID>
				<IE_NAME_UID>RIGHT</IE_NAME_UID>
				<ID>2</ID>
				<GET_SETTINGS>OFF_ON_Settings</GET_SETTINGS>
				<GET_SETTINGS_CONFIG>ASOBO_Engine_Starter_Settings_Config</GET_SETTINGS_CONFIG>
			</UseTemplate>
		</Component>
		<ParametersFn Name="OFF_ON_Settings">
			<ReturnParameters>
				<UseParametersFn Name="ASOBO_Auto_Define_Positions_And_Tooltips_Helper">
					<POS_0>OFF</POS_0>
					<POS_1>ON</POS_1>
				</UseParametersFn>
			</ReturnParameters>
		</ParametersFn>
	</Behaviors>
</ModelInfo>

hope somebodey can help here!
