The ones in the "wrong" place are those with several Th12s, not you. Fully active clans with more than 1-2 Th12s would normall be in Gold 1-2.
Your roster is the type that would be excpected in Silver 1. You will probably find quite a few of your opponents accounts don't actually attack, and they are also likely to have quite a few very rushed bases among their line up.
Having said which, Supercell don't appear to have changed the initial placement algorithm, while so many clans have got stronger since the initial CWL that most clans joining for the first time now should probably be placed 1-2 leagues lower than they would have been then.
