Found 2 orders; one in 2004 (Applied Job #o45405) and one in 2007 (Job # o71746). And the luck is with you. Normally our record retention is six to eight years after the last job (thus anything in the 2004-2006 range is in “jeopardy” anything beyond that has been destroyed and just yesterday they started pulling the 2004 records to be destroyed …. but it has been done yet ).

"yet" in this kind of sentence can have two different ways to use:
up to now: so far
He hasn't done much yet.
when it is used to imply the negative of a following infinitive
The team has yet to win a game.
Hence, you are RIGHT, it does miss "NOT" in the sentence.
If you don't want to have "not" in the sentence, you can write it as:
but it is (still) yet to be done.參考資料： self
