I had not rebooted, but I did after seeing your most recent question, and the problem still existed. After removing 29-language-selector- zh.conf under both conf.d and conf.avail directories, the problem also still existed. After also removing 99-language-selector-zh.conf in both directories, the warning message does not occur.
