I’m an invoiceninja.com user.
I encounter a problem when I edit an invoice or a quote, the custom fields are erased after saving.
The custom fields have been added in the settings menu / Products / custom fields. [Nature | exécutif, créatif]
I can see and edit them in the products items.
When I create a offer, I can edit the custom field and see the changes in the preview pane, but right away after saving, the custom fields are empty.
What am I doing wrong ?
