Created attachment 192439 [details] Sequenve of generated barcodes of added items After updating to v25.11 (from v24.11), the autoBarcode feature generates number with incremental value of +7 and not +1 as expected (see attachment). In v24.11 this worked fine. How to reproduce: 1. set autoBarcode to incremental EAN-13 barcodes in Cataloging preferences -> Record structure 2. set barcode.pl as plugin in Tag 952p in MARC bibliographic framework 3. create new or open existing record 4. add new item 5. click into p - Barcode field to generate barcode 6. repeat step 4 & 5
