Target file (word) partially translated

Hi, I'm using the new Studio 2019 and when I try to save the target file in word, the segments in the word document are not translated (they remain in English instead of being translated in French), even though they are translated in the xliff file (and they also appear translated in the word file created for external review). What is even funnier (kind of!!) is that the problem appeared a few days ago, so the first 120 pages are properly translated in the word file, but then, suddenly, the rest is non translated. My document has 400 pages in total.

ANy idea how to fix this? Tx, Cosimo.
