Hi Feralflora,
Thanks for your quick reply. I tried your recommendation but it did not really change anything in terms of the results I get. I played around with the data explorer and have - if I understand this correctly - the impression that the problem might not lie with the import. Below, you see that only a very short part of my zotero-note (which continues considerably beyond the first heading) gets recognised by the data-explorer. any further ideas?
cheers!
