I found 2 ways to reproduce this:
1st way is by having an admin update the config with the server/SP still running, the config would need values where you need less charge.
2nd way is by losing mass on your ship through docked entities:
If you have a 1000 mass ship with a 10 000 docked turret, you need a jump charge for 11 000 mass.
If you charge that amount, and then lose the 10 000 mass docked turret, your mass decreases but the charge of the jump drive doesn't update and stays charged for 11 000 mass, causing it to overcharge and this display issue.
