Never done this myself, so it's kind of a shot in the dark;
First thing I would do is ensure the Speaker Condition is still filtered properly, and Info/Response strings are in the proper order. Another possibility is hyperlinking to another topic may not have been translated the same, e.g. original; Abcdefg new ; Abcdefh. Originally Abcdefg was hyperlinked to topic Abcdefg, but the newer version loses the topic because of inaccurate translation to Abcdefh.
Meh... Probably not making much sense here.
It would help to post as much info as possible on a dialogue string to help troubleshoot this.
