why adb logcat can't show d/w/v logs but only e logs is working

Question

My adb log was working before. But today it just got messed up and only shows error logs. The d/v/w logs from other system/ other libs are also working. only my normal logs stopped working.

    Log.e("xxx", "onKeyDown")
    Log.d("xxx", "onKeyDown")
    Log.v("xxx", "onKeyDown")

here is the screenshot of adb logcat | grep xxx
