Legion Remix: Anyone else having issues getting credit for this? My achievement tracker says I have 4/8 currently but I've been flying around and gotten at least 20 different chests or more. Is this bugged?

Update: I still don't know know if this was a bug that's now fixed or I was just getting the wrong chests but I successfully completed this after a reset with some chests within the Thunder Totem sub-zone.

Not all chests count only the big ones.
