When I translate English to Uyghur, the warning message always show up. Like: $1 has not been used. Uyghur is a rtl language, if I change that to 1$ it says correct. So I'm confused how should I manage with this? If I saved as $1, the system automatically add a "FUZZY!!" before my translation. Which kind of expression should I use?
