Hi,
you are probably right with this:
- The two programs are using different style sheets
More like different version. CSL styles in JabRef are updated automatically while we are developing, so the nightly/master branch always contains the latest resources.
- The programs are using different style sheet interpreters under the hood
We recently changed the underlying implementation of the generator.
Regarding capitalization: I think the generator just doesn’t take capitalization into account for that style.
You might want to write a bug report here:
