I'm sorry you feel that you are alone. If there is an entire cemetery that needs a language reset, you can always do this by sending out a request through the help desk, as I do this on a consistent basis.
We set languages in cemeteries depending on the common language in a location. For example all cemeteries in the United States and Canada are set to English. However, you may come across a Jewish cemetery in Hebrew or a French Cemetery in Quebec. At that point if you send a request into support to change a cemetery language. Support can go through its channels to ensure this is done.
You will know there are no more English headstones to transcribe when you come across headstones written in another language. When this occurs if this headstone is Chinese in the United States, you set the language of the headstone to Chinese and the stone will be sent to people working in Chinese.
We are always working on website innovation. We are also always trying to create easier and better ways to do things for our customers. Please be patient with the process. This will only get better and better for everyone!
