Wrong Prononciation in Turkish Language

When I right click on a friend it says "Sunucuyu Sustur" but it should be "Sunucuda Sustur" just as the one right under it. Sunucuyu sustur means "Mute the Server" but it does not do what it says. Sunucuda sustur means "Mute in server". It just got my attention and I wanted to inform you guys. Have a nice day.
