Opening the dictionary deletes pre-saved translation

Since the already saved community translation are often wrong it is always worth to double check. The annoying thing here is, that often, but not always weirdly, opening the dictionary deletes the translation, that was already saved.

It would be better to let it stand and give the user the option to decide, wether he would like to replace it or not.

On another note, it would be great if people could just stop saving incorrect translations alltogether.
