[FIX] product: remove extra content option on dymo format label

Steps to reproduce issue:

1. Go to Products.
2. Select a Product with an existing Barcode.
3. Click on Print Labels.
4. Select Dymo as format, add Extra Content, Confirm.
5. Extra Content is not shown.

Explanation:

The Extra Content is pushed out of the label by the other elements.

Suggested fix:

Remove Extra Content to make up for lack of space. Approved by PO (thd) and already removed on other label formats.
