Latency would do it. It could be that languard is not waiting long
enough for returns from those ports, and is counting them as
filtered/closed. Look into your settings for languard and see if
increasing timeout values will help. Also try running the scan at a
slower speed. If the device is already doing something else when you
try to scan it you may not get a response in time while it processes
everything that came in before your connection request.
