Its related to Richelieus second turret blowing up two of its guns upon her first battle, with the first salvo.

"Rounds fired from this turret used propellant charges that produced less pressure than the ones used on the previous day and thus did not suffer bore prematures. However, these lower pressures also gave significantly less range than estimated which caused fire control problems. Richelieu fired a total of 24 rounds during both days of the battle but she failed to score any hits. A few days after the battle, the French attempted to clear No. 5 and No. 6 guns by fire, but No. 5 gun failed in the same manner as had No. 8 and the gun stuck in the recoil position at an angle of 15 degrees. After this, No. 6 gun was cleared by hosing down the charges and then removing them and the projectile through the breech.

The cause of these problems was eventually traced to a defective shell design."

Why they put medium range on the IMPROVED guns rather than the NORMAL guns.... likely an error.
