That is a standard tone stack and that is how they work,,i.e Normal operation.
Nothing wrong with the circuit. thousands of old fenders do that.

That's more like a Fender tone stack, although different values. Look at the Marshall tone stack. It's mid control is wired different so that it doesn't cut the signal when everything is set to 0
