Subscribing to a Wiki page: possible error

[Knightfall]

I'm having a bit of an issue with how the subscription system is working in conjunction with the campaign group pages I've created for the wiki. It allows me to subscribe to a page, but if I go in an edit the page again, the subscription doesn't remain saved. It makes me subscribe to the page every time I edit it. It's annoying, and I'm assuming that is not how it is supposed to work.
