Note my changes above. Two were simple spelling errors (if you had an English spell-checker installed on your browser, it would have picked them up). The other, which you might not know, is that we write numbers below 21 in words, not digits.

Otherwise, they're OK but I'd probably say "the following two pieces were missing". It's shorter and avoids the repetition of "packages".
