No problem really - they've just got a number of episodes to show whenever they get round to screening them. Whether they repeat some already aired episodes remain to be seen - I'm guessing like a lot of US dramas on E4 lately it's ended up going out at 2am so it should at least get a better slot than that. I suspect it's only being moved to E4 Extra to give it a bit of new content at launch.
