why zotero put the same author b before a?
I am writing a MS. I cite two papers of the same first author (let's say John.), why zotero put in the text the first appearance of John as "John et al., 2007b" and the second one as "John et al., 2007a". And in the Bibliography, the reference corresponding with "b" actually appears before the reference corresponding with "a". How this happened? Maybe I first cite the "a" before and then later I removed, but then zotero does not know update the order of the reference?
Which citation style are you using?
thanks for your help. It might be reasonable. I am using the Biogeosciences style. the case is as below:
because the journal asks to use alphabatical order, so the "a" is before "b" in the following reference, however in the main text of the MS, the "b" is cited before "a". From this point, the "b" appears before the presence of "a" might be reasonable.

But I do think we have some other citation errors for this journal, see a separate discussion thread by me:
