I think 'Grid2Options\GridStatues.lua' should be fixed.
around line #596

from:
local c = status.dbx.colors[type]

to:
local c = status.dbx.colors[type] or status.dbx.colors[L[type]]

Can I have the authorization to commit koKR localization and some other files?

Absolutely, the repository is open. Anything submitted via svn creates the next alpha version. I think I finally fixed the code issue correctly as well.
