Mouse.Target only returns Baseplate?

Hello, I'm having an issue of Mouse.Target only returning "Baseplate", despite me hovering the mouse over other parts. Removing the baseplate stops the code from working altogether, even when hovered over other parts. Help would be appreciated!

The script is a LocalScript inside StarterGui.

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local target = mouse.Target
local textlabel = plr.PlayerGui.ScreenGui.TextLabel

mouse.Move:Connect(function()
    textlabel.Position = UDim2.new(0, ((mouse.X+15)), 0, ((mouse.Y+5)))
    if target then
        print (target.Name)
    end
end)

Edit, I've attached a gif of the situation here; imgur link. What's weird is that it should be nil when pointing at the sky.
