Error message when Open for Translation

Hello,

When click on "Open for translation" to translate a word 2016 document, I get the following error:

Expecting element “Non Translatable StyleMappingRule” from namespace http://schemas.datacontract.org/2004/07/Sdl.File Type Support.Filters.MicrosoftOffice.Core.Common:..Encountered “Element with name “non TranslatabbleStyleMappingRule”, namespace “schemas.datacontract.org/.../Sdl.FileTypeSupport.Filters.MicrosoftOffice.Common”

It does not let me open the document. Is there a way to fix this error?

Thanks,

Talia
