Hi

I have a large library&nbsp; (1400 references) from a systematic search, the data has been exported and imported (Rayyan, Endnote Import File) and I have a lot of missing years showing blank (500+ records). Not sure if they were lost in process or were missing all along.&nbsp;

I used ‘Find Reference Updates’ for blank fields to fill in the gaps.&nbsp;EndNote says the process is complete and all references up to date but the missing years have not been populated, which seems odd as most are&nbsp; journal papers with DOIs and the years are clearly visible in the citation downloads for the sample I’ve manually checked so far.&nbsp;

Any suggests
