It just highlights the tiles, it's not meant to cancel if you deviate from your route (like for example for a secret room). You can toggle color on individual tiles to get rid of it if the route no longer applies to you.

How? There's nothing in the route planner for that

And I didn't deviate from my route; I planned a new route, which left the old route highlighted.

It's just something you can do normally by right clicking on tiles to toggle through (or get rid of) colors in the map. I don't remember what it is for controller/mobile.

(But yeah an option or default to clear existing green tiles when making a new route would make sense, hopefully Shu would think it's a simple tweak)

There's a "Clear Highlight" that nukes all color markings (blue, green, red) on your map. Tap A on controllers to cycle colors too.
Route planner doesn't clear all existing highlight colors because players can pre-mark some tiles that they definitely want to go (or definitely don't want to go) to help planning. There are also cases where players might plan half a path or have Fog of War (show only 3/2/1 ring of tiles around you) instability on.

But yeah I might make an option that auto clears existing "green" markers in a later update to prevent confusions.
