In the author year csl, for the same author and year, and disambiguate-add-year-suffix="true" the preview is different with zotero or word.

It shows
(FAO, 2013)
(FAO, 2013a)
(FAO, 2013b)

The correct is:
(FAO, 2013a)
(FAO, 2013b)
(FAO, 2013c)

Is this a bug?

Hi,

sorry by my delay on response. I'll investigate the behavior and send you a feedback. I just prepared a new function and now this should be my priority (except for eventual bugs that seems more critical).

Hi, @redleafnew
after this long delay (sorry, in mean time I moved from my old home and this consumed much time), I figured out the reason of this behavior. In fact, this was a bug, thank you for reporting and help to make the extension better. In this week I will release an update with the bugfix.

Thanks
