We just launched a new journal https://biocomm.spbu.ru on an OJS 3.0.2 and faced the following problem with EndNote “how to cite” export.
Page numbers are merged with number of the volume. Thus we get in enw-files:
%P 6–18%V 62
instead of
%P 6–18
%V 62
I checked a couple of other journals on 3.0.2 (http://godisnjak.ff.uns.ac.rs, https://ojs.hse.ru/index.php/sociologica). The situation is one to one. So this is an obvious bug that needs to be fixed.
