validation error help in lay terms

Hello Sigilers,
Please help this inexperienced Sigil editor who has very little knowledge of HTML with this validation error:
"The <reference> element's "type" attribute has value "copyright" which is not an OPF-specified value. Either use a predefined type or start your type with "other."."
I'm trying to correct epubs that were created by a conversion company. I'm starting to suspect that the validation errors I'm finding when using Sigil are caused by the conversion company.
Any help would be much appreciated.
