Original setup

But when it's fast replaced manually, this happens

The upgrade planner works as intended, keeping the original lane preference

inserter's preference is not part of settings but part of its direction/mirroring. Are you manually building normal inserters or flipped inserters? Inserter gets whatever your cursor is when building making this not a bug. It would be easier to explain with a recycler but it behaves the same with drills and inserters where cursor's flip affects flip of the entity built.

I'm manually placing the inserter over the existing one, I can change its lane preference, but originally when placing a new inserter, it suggests a default configuration. I think it would be good for them to copy it over to the new entity

I am going to move this to Not a bug as this is currently working as intended: inserter inherits flip state from cursor, not from entity being overbuilt.

I also stumbled over this and can accept that is not a bug. However, I still want to add two argument to change it: 1. When you quick replace assemblers, they preserve their rotation. 2. You could preserve inserter flipping while normal overbuilding, but force the direction of the cursor when shift+overbuilding.
