The interface remains unchanged

I know the interface can change every time I change some code (I changed the language and the interface automatically changed too), the problem is that i have tried to deleted and changed code in “or-header.ts” (item inside “toolbar-top”) but the interface didn’t change.

  1. Is there anything i can do to customize it
  2. Is there any command i need to use to rebuild the UI (i have run ./gradlew modelWatch and tried ./gradlew clean installDist but it didn’t work too)

When running a local web development server using npm run serve,
it automatically compiles the code, and refreshes the web page. (hot reloading)

FYI: this should not be related to ./gradlew clean installDist

On my machine this all runs fine, so no clue what is happening on your machine.
Is the (detached) web server process is running correctly? (not closed nor crashed)

Also, have you verified all the prerequisites have been installed and configured?
