As for your second question, you said you "renewed" your visa. That means you got a new visa, so it should show the term of your visa. It sounds like you have your re-entry permit in there as well. That is all you need. Imagine somebody who has been living in Japan for 20 years, jumping between different vocational visas. If he had one good for 2008-2010, why would he need to show the one from 1980 that he entered on?
