Before I submit a bug report for this (or come up with a possible workaround), could you explain why those articles shouldn't now have a DOI? AFAIK, this won't or shouldn't interfere with any part of the publication or article-finding process; and you can always register the DOIs with eg. Crossref, or presumably with whomever your DOI resolver is. Further information would be helpful.
If you deposit all doi meta for all back issues then , we have pay a lot of money to crossref. For example, our journal start from 1970. We can put all back issues after 1999 on line . But if we assign every article of back issues a doi and deposit on crossref , then we have to pay $0.3 (or 0.5., I forgot it) * article numbers before 2009. And we can not offer the money.
