Frequently LX and LH will not allow you to ticket on UA (016 stock) if there are no UA (metal not codeshare) flights - and they also do not share all of their inventory with UA - so you can frequently only buy the flights from them….
The flight numbers you see are the UA codeshares for the native flights - don’t worry about….
