Articles generated from RSS feed remaining the same as in the origin page

Hi, when I set up a bulk post creator based on an RSS feed the system unfortunately not creating a new title for my article, but uses the same one as it was on the RSS feed. First I only recognised that it is not translated from English, but later on realised that it is even the same as in the original in the feed. Is it a setting or how do I get rid of these original titles and get a new one translated to my target language?   Thanks!
