When you use the New Magazine or New Anthology (or presumably other New... links) to start entering a pub record, the type pull-downs for individual content items do not have "Editor" on the list. (This is a fairly recent change, and a good idea, because EDITOR records need never be manually added to a new pub.) But if there are more than the default number of content items present, and the "Add titles" button is used to add additional content-item fields, then the pull-downs for those added fields DO include the "Editor" option. This complicates data entry because on the first group one can tab to the type field and press E once to get an ESSAY type, but on the added fields a user must press E twice, and if the habit from the first section causes a user to press E only once, a pub may be saved with a spurious EDITOR record, which will need correction.
