Ultimate Facebook posting error, help needed

I'm sure I am missing a simple setting here, but the plugin posts to my personal Facebook page and not my website fan page. Where are the settings to direct to post to the correct area?

This plugin seems to be amazing, but I have seen a simple feature to direct the the plugin where to post to within similar plugins I have previously used...it isn't as simple to set up in this one.

Looking forward to any help anyone can give with this.

As an aside, it may be worth noting that my personal profile currently has three pages attached, each which will hopefully link to three separate websites. On creation of the Facebook app to use with Ultimate Facebook, I created the new page from the Facebook app itself, obviously logged in via my personal profile (FB doesn't allow it any other way?) so is this the possible issue?

Thanks in advance,
