Scoreboard Coden Minecraft?

Hi Guys I have a farge and although I've scored a scoreboard and now I have the problem that if I give myself money it generates a new line but does not erase the old one How can I fix it?

Try to backup and delete the world. If you have used command blocks then check them if you did not type in the error.

Hello that has nothing in common that is due to the plugin that deletes the old line but not updatet the scoreboard and makes a new line
