Layering another type of paint on cabinet/how to fix
Yes, that is normal with brushing that kind of trim.  I had a door in a Victorian that drove me bananas for days.  Just add a 3rd or 4th coat and don't give it any more thought.  And be glad you're not painting lavender over deep purple lol! 

You could sand it gently, but I'd be VERY careful around edges and corners; it's easy to blow through all the layers and expose bare wood, and then you have to prime all over again.  

Also, I see where you hot-dog-rollered it and called it good on the flats.  That leaves a texture that is different brush vs roller.  To avert this, I use a technique called roll and tip, where I hastily spam down paint with a roller and immediately swish over it with a brush.  

This provides brush stipple instead of roller stipple, which is consistent across the piece; however it also creates a bit of a "hybrid" for coverage, more even than pure brushing but not as even as pure rolling.  It also lets me use the end of the hotdog to lay paint in the grooves, which is a big timesaver since I need to dip the brush far, far less, essentially only at the start of the tip-out.
