Ultimate Facebook Destination defaulting to Me instead of a specified page

Hi y'all - here's my issue: I've got a multisite, and while setting up, in both network settings and single site settings, I've tried to select default destination for autoposting to facebook to our PAGE, not any of our personal accounts' walls.

Issue is that destination selection seems to work fine on the actual new post page, however instead of being the page destination I've tried to specify in the settings, it reverts there to "Me". If we change that destination to the page, then it works. The problem is that we really need the default to be the page as we've specified in the settings. Having to manually specify the destination each time anyone ever makes a post doesn't work for us. Is this a known issue? Did we mess something up?

Thanks all very much for your time and consideration!
