The problem is coming from "Module" element override.
solution:
1) search /language/XX-XX --- your language folder for that TERM, i.e: "read more"
open every file contains that TERM, and if not being translated, do all !
2) if still not, You dont have language file in XX-XX folder, then, copy from en-GB, rename it and do the translation! (dont forget upload the translated file to the community :P )
