New 1803 Update (July) - Autoselects Resolution Scaling?

I updated Windows yesterday (v1803, July update). I had to reset my resolution scaling to 125% yesterday. I shut down the computer and this morning plugged it into my dock, which has a 27" monitor. It booted up to 100% scaling.

Not sure if the update introduced a way to customize scaling if it's attached to a monitor or if it failed to save the resolution scale (hope this will not be a recurring issue if so).

Maybe I had previously put both at 125% and didn't realize it.
