Hello feejo, Does this happen with the default layouts as well? If not, then most likely the fields are not linked. Open the layout in the designer (Tools > Design Layouts > Contact), and look at the white boxes next to the field name. If they are empty, that means no field is associated. Click on the white box, then select the field to link it to. This can happen when you bring in a layout from a different database since layouts are database-specific.
