Route planner ignores "Preferred" charging networks

I have noticed a recurring issue with the route planning algorithm regarding charging network preferences.

When planning a route, there are locations that host multiple charging stations from different brands. Even though I have set a specific network (like Astor) as Preferred with the heart icon, and another network (like ZES) as Not Preferred, ABRP consistently bypasses my preferred choice and selects the non-preferred one at the same stop.

This happens even when the preferred charger offers better specifications, such as a 400kW Astor charger being ignored in favor of a 350kW ZES charger. This is not an isolated incident between these two specific brands; it happens across various networks whenever they share the same charging location.

The algorithm seems to be ignoring the user's network preferences and power advantages in these scenarios. Could you please look into how the routing engine prioritizes overlapping stations?
