Shadowlands intro quest bugged?

Hey i try to skip shadowlands because i had the option to skip the whole maw quest part and so on, but when i arrived in Oribos the NPC didn't talked to me so i relogged and it began the normal shadowlands quest now i tried to talk to the NPC but had no option to skip. and everytime i do a quest it tells me i completed it once but this is a total lie i started Retail WoW 2 Weeks before TWW release. I'm sorry if this is too much but to be honest i don't want to waste 9+ hours (thats the estimated time if google is correct) to complete Shadowlands.

EDIT:

To clearify things. I never played back then in Shadowlands. In Dragonflight i used a Character Booster when i started because i got one from the special offer i used. Now if i do with any Character those Shadowlands Main quest, there is a small text at the end of the quest when i need to accept them and this tells "The warband completed this quest already" (could be wrong translated because my game is not set to english sorry) so i'm kinda confused but i will need to stick to the Main Story and complete it normaly but can some1 atleast tell me how long it will take?
