Switch DLC

Hi guys sorry i tried to look on the internet to learn which are the available dlcs but i i found it pretty confusing

like i don’t understand why on the official site not all the dlcs can’t be downloaded on all platforms, like does it mean that they will arrive then or that on the switch version they are already included(for the “a new power awakens set”)?

sorry if it is a stupid question but i am pretty confused😅
