David, before shipping cuttings, all the large leaves should have been removed, leaving only the small, terminal leaves. Regardless of shipping, those large leaves would be lost while the plant is rooting, which is perfectly normal. The plant isn't in any sort of "shock" or even dormant. It is simply channeling its energy into growing roots. I hope this information helps you understand the mechanism of rooting and lets you know that you did not do anything wrong. I assume your plant rooted in the spring?
