A Vault document field contains a blank value when it should have a value assigned to it by default.
The document field in question is hidden at the time that the document is created.
If a document field is configured to be hidden at the time the document is created (due to a Field Dependency Rule), the default value for the field is not applied to the document.
There are two possible solutions to this problem:
- Manually set the value of this field at some point after the document is created
- Remove the Field Dependency Rule that forces this field to be hidden at the time that the document is created
