I use the ignition version 8.1.25 , I created a EquipmentSchedule, and then I try to switch language to zh , but it show an component error , I try to update 8.1.44 ,it's working , so I want to know which version you fix this issue , and if I want to use 8.1.25 ,is it possible to change something to fix it .
Just curious, where do you pass the language into the EquipmentSchedule?
In any case, for Chinese I guess you should set zh-CN. Have you already tried?
It's working ,Thank you, bthey used "zh" to locale language name , it's working in all of labels ,so I didn't try to use "zh_CN".
In general, if a bug is fixed in Ignition, you have to upgrade to get it. 
But there are other issues when we use the higher version , out team don't want to upgrade .
Sorry, you are out of luck, then. You have to prioritize which bugs are most important to you, and use a version that fixes those.
