Planned SOC falls to zero in tunnel

The planned SOC falls in or around the Gotthard road tunnel to zero. It could be that ABRP takes the topography above the tunnel into account and not the actual steepness inside the tunnel. On the first part of the route I’m passing the tunnel with a higher SOC and there’s a smaller dip, but still there’s a dip.

Although there SOC goes up afterwards that could lead to lower SOC estimates and could falsify route planning.
