There is in koha-tmpl/intranet-tmpl/prog/en/includes/ill-batch-modal-strings a sentence "Unable to updatecreate batch request". Should it be "Unable to update batch request"? The sentence above this one is "Unable to create batch request"
Thanks for reporting, Anneli! Found a duplicate with a patch. *** This bug has been marked as a duplicate of bug 35404 ***
Anneli: I translated with the correct string in Spanish. The fix for english will come on the first point release.
