Hi Emma, the custom module was written by my company 4 years ago. The module is an interactive questions / answers and works perfectly, the problem is the backup.
And I forgot to add that the URL module also fails to backup if the external URL is longer than 31 characters.
I have tried everything and I don't see the problem. If, for example, the module title is 31 characters long, it's fine, it appears in the backup XML; if it is 32 characters long, it appears blank in the backup XML. And this for each text field.
