Hi Michael
The product label printing is not so handy in Odoo. We have got this a few years ago and have developed a free Odoo app that allows Odoo print labels in convenient way. You can specify the quantity to print for each label, a language, and select one of two custom barcode product label templates.
If you need more, to have the ability to create, edit, and design the own product labels, take a look at the Product Label Builder app. With this solution, you'll be able to create product labels with images, barcodes, QR codes, include fields from Products, Stock Pickings, Purchase and Manufacturing Orders, indicate a pricelist to specify prices on labels, and include or not taxes.
Best regards, Yurii Razumovskyi.

Does anybody know how I can solve this issue? Thank you
If you switch the log level to DEBUG, can you see any hints in the log?
If you individually print any one of these products that is missing in your list, does it show up?
