I was looking at the ShipComponentDefs.xml and came across this entry:-

 
  <ShipComponent>
    <InternalName>AssaultCarrier Module</InternalName>

There seems to be an extra space in the InternalName, DisplayName, Description. Other files that reference this component like, ShipBluePrints.xml apply the reference without a space:-

    <RequiredComponentType>AssaultCarrierModule</RequiredComponentType>

Or ComponentClassDefs.xml :-

    <UniqueID>AssaultCarrierModule</UniqueID>

No idea if this is actualy having adverse effects in game or not. Its the only entry in ShipComponentDefs.xml that has that extra space.
