In Koha version 3.03.00.004 in the Administration if I go into Tools- Label Creator->Manage Batches->New Batch Then do a search by a creation date I am getting 77 returns. If I press 'Select All' all the checkboxes on that page are being selected. However when I press the 'Add Checked' button on the top of that page only the first item is being added to the batch.
This issue is not present in master.
