Region 3 does not give consistent results, what is the problem?

I am trying to make a gui pop up when a player enters an area and with the research that i have conducted, i have been advised to use Region3 to deal with detection. I have a folder in the workspace containing two locations that i'd like to detect. Upon testing, if i step in one part, everything works perfectly fine and distingushes whether im inside or outside. However if i step into the second part, it says that i am in the part and out of the part straight after :(

local locations = game.Workspace.Plots:WaitForChild("Border")

local Found = false


while wait(1) do
	
	for i,v in pairs(locations:GetChildren()) do
		Found = false
		local region = Region3.new(v.Position - (v.Size/2),v.Position + (v.Size/2))
		local parts = game.Workspace:FindPartsInRegion3WithWhiteList(region,game.Players.LocalPlayer.Character:GetDescendants())
		
		for _,part in pairs(parts) do
		 if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
			
			
			Found = true
			break
		 else
			
		 	Found = false
		
		end
		end
		
		
		if Found == true then 
			game.Players.LocalPlayer.PlayerGui:WaitForChild("HomeIcon").Enabled = true
			print("In")
			break
		else
			game.Players.LocalPlayer.PlayerGui:WaitForChild("HomeIcon").Enabled = false
			print("Out")
		end
		
	end
	
	
end
