season 8 episode 1??

I'm watching through for the first time on the discovery+ app. I just got to season 8 episode 1 and the "previously on" really confused me because it was a bunch of stuff I never saw. I thought maybe the app glitched and skipped some episodes or I skipped a season. But no, it really was the first episode of the season.

I googled the season 8 episodes and on Google this episode is called "Growing Up and Moving Out" and the description is all the stuff they said happened previously. The title on discovery+ is "The Hardest Parts of Love".

Really confused does anyone know about this or have an explanation?? I wonder if they edited the episode when they put it on the app I just don't know why.
