On some forms the default preset 'Default selection' has been modified, for example on the Customers, Suppliers, Personnel and Parts forms. If you have any custom presets based on this preset, you should implement these changes to those presets as well. The reason is that custom presets must always contain at least all of the fields of the 'Default selection' preset of a form. When you use a custom preset that has not been modified yet, a message will appear saying that you need to add the missing fields to the preset.
