Hi Leonardb,
As the workflow shared above, you have first opened the pdf document then converted it to word doc and after converting to word document you are editing the word document.
If I understand correctly, you are editing the word document after converting from pdf? If yes, then try searching the file in the MS word files. And might be in the download folder of system library.
1- Once the pdf document converted to word you either need to download or save the pdf to system library.
2- When the word file was edited and saved it must be saved in the word format itself.
3- For detailed explanation please refer- Using Adobe Export PDF
