[Resolved] translation desapear when update original

Hi. Im new with this plugin. Actually im using it first time. I figured out by method trials and errors how work with this plugin but i have also some questions.

When i alredy translated some page, like on screenshot, and then i will update original english content, then translation of this content desapear after modification of original page. How to keep translation even oiginal is modificated? This is very important for me, because when im modificated some part of original i would like to also have possibility modificate this small part of translation version, without writing whole text from the begining.

This is possible?
