Keep getting error for Ignoring unreasonable position

So I have create a prop_physics and I have set the pos to 0,0,0 which I confirmed it is not clipping anything in the world/map. Still I keep getting the error “prop_physics[184]:SetPos( -1.#IND00 -1.#IND00 -1.#IND00 ): Ignoring unreasonable position.
Nav File is wrong or something (4)”. The nav file may have something to do with it but I have already re done the nav file.

Full Code:
hook.Add( “InitPostEntity”, “some_unique_name”, function()
local box = ents.Create( “prop_physics” )
box:SetModel( “models/bonkaddict/apb/jokerammo/ammovendingmachine.mdl” )
box:SetPos( Vector( 0,0,0 ) )
box:Spawn()
function box:Use( c , a )
local Window = vgui.Create( “DFrame” )
Window:SetPos( 5, 5 )
Window:SetSize( 300, 150 )
Window:SetTitle( “Test” )
Window:SetVisible( true )
Window:SetDraggable( false )
Window:ShowCloseButton( true )
Window:MakePopup()
end
end )

Any help would be appreciated.
