B4R Question Wemos D1R2 pins input states

[Tayfur]

I cheked manuelly all pins for D1 ... D8;

I looked 2 diffrent point.

D4: I connected ground; same time wifi's led on. is it connect wifi led? how can I cancelled (if possible)
D8: I connected ground, and never changed state D8.!! Why?

pin8.Initialize(wemos.D8,pin8.MODE_INPUT_PULLUP)
pin8.AddListener("PIN8_Changed")

Private Sub PIN8_Changed (State As Boolean)

    Log("pin8 changed",State)
  
End Sub

I looked first run on myboard.

Log is >>"pin8 changed0"

But I dont touch this pin!!! this pin special?
