Visited on February 1st and charged with Tesla Model S, no issue.
I couldn't check the letters of group 1, but from what I see the numbering seems to be the groups 1-3 from left to right, but the letters from right to left: 1D, 1C, 1B, 1A, 2D, 2C, 2B, 2A, 3D, 3C, 3B, 3A. Based on my pictures from 2023 that seems to be the case in group 1 as well.
