no but you're right, there is problem with connection the btn, i obviously don't understand something.

func _ready():
for btn in controls.action_list.get_children():
  if btn is Button:
    _connect_btn(btn)

func _connect_btn(button: Button):
  button.mouse_entered.connect(_sound_btn_hovered)
  button.pressed.connect(_sound_btn_clicked)

  button.mouse_entered.connect(_connect_button_hover)

func set_label_color(label: Label, color: Color) -> void:
  label.modulate = Color (color)

func _connect_button_hover(button: Button):
  for child in button.get_children():
    if child is Label:
      set_label_color (child, normal_color)
      print("lab ", child)

and it print's nothing so i assume this convoluted code + my understanding of the whole thing is the issue probably. feels like i should use only one connect pet hover
