since your housing is 1 bulb, make sure you are not pulling the high beam switch all the way towards you. This will turn on the highs and lows.
Remove the problem bulb and look at the filaments, my bet is the high is burned out.
When you think you are turning on the highs, you are turning on the lows and one high, some cars turn off of set of beams, others dont.
Pull the multifunction switch towards you fully until the light comes on and then let go, you should see the beam in the lights move up if you do this at night. There is no other way for your case to work if the bulb is fine.
Some new hondas have a self test where if a high beam bulb is out or not drawing enough current it will just keep one side on, ie if you replace the bulbs with leds, then only one side works, but thats a whole other reason ... etc. I would replace the bulb.
