I'm also seeing this issue on the 2.0 release of Storm.
From what I can tell, the "prefix" and "fullname" fields in the organization content type have been deprecated, but the Invoice template is still calling them for the Bill To section. Currently, if you have an organization that was created pre 2.0 upgrade, the field is populated with data that can no longer be edited once you upgrade your installation to 2.0.
Also, the invoice template doesn't print the name of the organization.
