Word problem when using the Import for bilingual review in Trados Studio
An example of how Word doesn't always remove the paragraph breaks from a word file if you mistakenly add them and then remove them afterwards. So a lot of care is required when using the export for bilingual review process.
Importing with the external tool, SDLXLIFF Converter for Microsoft Office often solves the problem as this seems to be less picky than Studio. You can find this in the Navigation menu of Studio in the Welcome View.
