[TYPO3-ttnews] INVALID VALUE for Archive settings

[Chris Kievid]

I updated to latest version and it showed the tt_news items, then I 
added some TS, and tried relocating the tmpl file,and after these action 
no more tt_news display. So I removed the TS and restored tmpl settings, 
but no effect. Then I noticed this Archive settings (for LIST)

[ INVALID VALUE 
("LLL:EXT:tt_news/locallang_tca.php:tt_news.pi_flexform.archive_nonarc") ]

When I changed it to 'Don't Care' it showed tt_news again in FE.
Any idea what his meant, and what i did wrong?
