Lila if the translation of the main part is correct we can accept the translation, which I did. Feel free to reject it again if the translation was wrong too. Rejecting a translation just for the title can discourage the new members who make their first translation on cucumis ^_^ .
There are 2 possibilities to manage this case :
1-You edit the title yuorself and accept the translation
2-You post a message like you did, asking the translator to modify the title, without rejecting.
