Guild Wars 2

Currently I’m at 0 unspent trait points, 1 unspent skill point. The cheapest skill I haven’t purchased yet is 10 skill points. But the icon for the hero window, and the skills and traits panel within it, have the exclamation point saying it needs my attention, despite there being nothing I can do there.

Shouldn’t this only show up if I can spend skill and/or trait points ?

This is happening on one of my characters (and only one), who is a Norn Mesmer. Incredibly minor, but surprisingly annoying!
