I'm trying to use publicly-available OIS/IRS clearing data from CME (ftp://ftp.cmegroup.com/../../irs/) and LCH (http://www.lch.com/en/asset-classes/otc-interest-rate-derivatives/volumes/settlement-prices-swapclear-global#usd) to bootstrap discount and LIBOR curves. The data between the two (for 9/27/17) only seems to line up for a few of quotes; otherwise CME seems to be way off.

How should I interpret this disconnect for the purposes of bootstrapping curves?
