I'm using checkcites v2.5 and I discovered that in my case it does not list unused refs. I have a multiple (with inclusions) files book and a single .bib file, I generate the .bcf then I run checkcites obtaining a list of 2349 unused items... but my .bib contains only 2146 items! (I do not have duplicate keys, checked with jabref) Anyway I random checked some of them and I can confirm that checkcites lists both unused and *used* references, e.g.: ``` ... => trentini2020cittadinanza ... ``` but in the .bcf I have: ``` ... <bcf:citekey order="2" intorder="1">trentini2020cittadinanza</bcf:citekey> ... ``` How can I help in tracking down this issue? Thanks
