Ach Tracking Not Saving?

[BadCompany]

As of a couple of days ago, my achievement tracking resets on log out. Also, it displays one toon's tracked achievements on all my different toons on the rare occaisions that it does save which ach's are tracked.
I only track achievements on my main, and they disappear at logout. And when I go to an alt toon, it has the same list as my main had when my main logged out.
Anyone else having this problem?
