The terminal claimed to be 5M + 2M/L stands when unlocking but L stands were not available once unlocked.
The L stands are at the gate you didn’t unlock yet.
2 L stands and 1M on the right side and 4 Ms on the left.
Stands 22 and 23 are L.
Thank you! I seem to have misunderstood the unlocking description if that is the case.
