Recently, Zotero has started incorrectly citing court cases in Chicago Manual of Style (full note without bibliography). There are two problems I see:

1) The "v." separating the parties has become capitalized, even when it is entered in lower-case. E.g. instead of "Brown v. Board," the citation reads "Brown V. Board."

2) In subsequent case citations, the volume number and colon appear. (This seems to be a recurring problem, similar to one that was put to rest a year ago, under the forum heading "Incorrect subsequent case citation - Chicago style.") E.g. subsequent citations of "Brown v. Board, 347 U.S. 483 (1954)" read "Brown v. Board, 347:." or "Ibid, 347:."

Any thoughts on this?
Thanks!
