Guild Wars 2

So I felt like doing the Ascalonia reward track today but for some reason I can’t reactivate it, even if I unlocked it by doing the story mode in pve. In the picture u can see that my mouse is on top of the track but it doen’t give me the option to reactivate it.

and on this pic It shows my locked track which I have none.

I had never done the story mode and had the same issue. I was trying to complete the armor and weapon sets for the new collections. I had to do the story mode to unlock it. Similar issue maybe, maybe not. Not sure if you have done the story mode but I unlocked mine and have been doing this one for a few days now. Hopefully it helps.
