Thread:VisualEditor/Feedback/Problem with parameters of zh template

I recently used VisualEditor to add a zh template to Confucius Institute in this edit. I selected the "s" and "p" parameters, but for some reason VisualEditor added the parameters "simplified Chinese" and "pinyin" instead. These parameters are evidently not supported by the template, so it didn't display correctly until I used the source editor to change the parameters to "s" and "p". I would appreciate some help understanding what went wrong. Thank you!
