I noticed this issue when racing at Maple Valley last night. If you select a grid position, for example, 3rd, the UI will tell you that you are starting on the right hand side of the grid, behind 1st place.
However, the grid positions are reversed at Maple Valley, and I’m sure at other tracks as well. This means that you are actually placed on the outside.
Please adjust the starting grid graphic before the race to reflect the actual grid slots at the track.
