Why can I only paste from local to remote only one time?

I hope to paste something from local to remote machine. But I only operate one time. After the first time, if I want to copy and paste new content, the remote machine only show the content of first time. That is to say, only the content of first time are stored in the  buffer forever. Unless I disconnect and connect teamviewer again, I can copy and paste new content. It make me feel much trouble. Can anyone help me? Thanks.
