MacBook Pro 2018 in 24/7 nightmode - cursor on external monitor not in nightmode Just got a MacBook Pro 2018. Upgraded from the 2017 MacBook Pro

I use my MacBook Pros in nightmode 24/7 since the bluelight hurts my eyes. I enabled nightmode on my new macbook pro and hooked it up to an external monitor but the cursor is unaffected by the nightmode changes.

I checked my 2017 and 2012 macbook pro and both change the cursor as well on the external monitor, just not the new macbook pro...

Any ideas?
One quick thing you could try is resetting the NVRAM.

To reset the NVRAM on your model MacBook Pro follow these steps: 


Shut down your machine. Yes, a full shut down, not just logging out.
Press the power button and then immediately press the commandoptionpr keys. 
Keep these keys pressed down for at least 20 seconds!
Let go of the keys and let your MBP reboot normally.


Note: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).
