Thanks for the report, Tiffany!

Numeric citations weren’t well-tested, and two-column PDFs (which I suspect is what you uploaded) are tricky, with characters from one column ending up in another. We made a fix that I think should solve your problem (but without your PDF I can’t know for sure).

Then, to test further, I got 15 publications from each of _IEEE Access_, _IEEE Open Journal of the Computer Society_, and _IEEE Journal of Translational Engineering in Health and Medicine_ and tested those, and found a couple other issues, like numeric ranges being reported in square brackets (like “[80–155] mmHg”) being erroneously identified as citations. There were a few others, but they are too esoteric to be interesting, I think!

Please reload the page (the Release Date should be today) and try the file again. If it still doesn’t work, please send me the file and I’ll figure out what the problem is.

Also, I put you in a free trial group, so you should now have 1000 look ups per month instead of the 50/day limit you just hit. If you need more or are interested in a trial for your department, please contact me via direct message (or email [jay@literatecomputing.com](mailto:jay@literatecomputing.com)).
