Guild Wars 2

I put this up already but here:

My gliding Basics says “Need 4,294,967,295 more mastery points to unlock this ability.”
I’m trying to train my Glider Basics. I had actually finished it, and the bar was (still is) full. The mastery point symbol next to it is white, and playing guild wars before, I know that I’m supposed to be able to click it and unlock it. My next mission needs gliding Basics completed to continue, and it also says i haven’t finished it yet.
I tried training something different from central Tyria, and that doesn’t seem to be training either.
This is definitely not just my computer, the issue shows up on all my PCs.
Looking up this issue on the internet, it seems all that comes up are page links that, at the bottom, say Missing: 4294967295. Not sure that’s related at all.
I’d like to know if this if anyone else has this issue, or if it’s even fixable.
