Plans additional stop at another close by but more expensive charger

https://abetterrouteplanner.com/?plan_uuid=24d0cc63-405e-4ca6-87e8-b0ff90123867

Plan was generated for an ID-buzz. I manually selected EWE-Go charger in Rhüden where i charge for 51ct/kWh but ABRP plans a 34 minutes charge at the Tesla supercharger 900m before the selected charger where cost are 64 or 69 ct/kWh depending on arrival time. It does that despite I preferred EWE-Go network over Teslas SuCs
