The target document rendered by MemoQ does not retain the same format of the original document.
I had this problem for weeks until I noticed that the documents I am importing for translation through memoQ were DOC types. After I changed the format to DOCX, the target documents were in the correct format. Not sure if this is the solution for all such formatting problems.
Also, perhaps the user needs to uninstall the MemoQ and upgrade to the latest edition.
