Why The East Coastway: Brighton - Eastbourne & Seaford Route (purchased On Tsw2) Is Missing In Tsw3?

I bought the route on TSW2 as well as other routes that were normally imported on TSW3 but the only one missing is that one there (East Coastway: Brighton - Eastbourne & Seaford). I don't know if it is intended or if it is a bug; maybe the route is already included in another DLC? I'm not familiar with the English routes so be patient please. Thank you

 

As has been pointed out, DLC that is carrying over can take up to 24 hours to show up.

 

Thanks for the reply squerble
