Cannot load a specific guide

[Dysheki]

I'm at 90% of the Tanaris (47-49) guide and I was curious how much was left so I arrowed through some of the final steps but accidentally went too far and it loaded The Hinterlands guide instead. I closed The Hinterlands guide and tried to load up Tanaris again, but it just ignores that and loads The Hinterlands automatically. How can I get the Tanaris guide back up for the last few steps?

Answered my own question, but not a fan: I had to close The Hinterlands' guide and then reload UI. Then it allowed me to load the previous guide.
