can you post a picture of your problem plus version of NPM you are running on, please? As we are supporting Japanese and German localization it might happen that some of the strings are wrongly mapped and appears in the product. Double check your OS and DB locales are EN. Also check that your primary locales in registry are also en ( HKEY_LOCAL_MACHINE\SOFTWARE\SolarWinds\Orion\Core/LocalePrimary).
Thanks for your reply. NPM version is 10.3. Because there are some security restrictions. I can not post internal datas. The OS and DB locales are Simplified-Chinese. The IM software is Tencent RTX 2008. The point is the same chinese strings send from Basic Alerts are correctly showed.
