I use SRD_TranslationEngine and would like to know if there is a quest journal plugin that can be easily translated with it (or another way). YEP_QuestJournal is great, but I couldn't find a way to translate most of the text within it.
I used the srd translator a lot in the past. Although it's amazing the interface for translate, it has some issues like that you faced and many other surprises.
So I moved out to Iavra Localization instead.
But also there are other plugins to translate the game too, that was released but can't remember the name.
