Ultimate Facebook not validating api settings at multisite network admin level

I can get my API settings to validate on the subsites, but not at the network level.

I would prefer to only use this globally, as I expect users at one subsite will engage in other subsites.

I tested the info on subsites peeryproject.nbrhdwkshp.com and the base nbrhdwkshp.com blog - and it validated in both cases just fine. I've deactivated the subsite installs, after clearing out the fb api data, and have only activated the plugin at the network level, and the exact same api info won't validate there.
