[addon] ElvUI - Details Meters Not Showing

I have ElvUI installed and the AddonSkins extra. I've enabled the embed in one window option, but Detail! meters never appear. Additionally, typing any of the /de commands in chat doesn't work; for example, /de options does not bring up an options window for Details!, nor does Details! show a configuration window after a fresh install of the addon. Any thoughts on how to fix this? I'm using Wowup as my addon manager and installing via URL from wowinterface.com
