47.17 Fuel tank "magnitude" displaying improperly in-game?

[gsparks3]

Environment

47.17, standalone Megamek
Windows 10
Java 11.0.10

Description

On initially selecting a map and viewing it in the Megamek lobby using View Game Board, Fuel Tank hex tooltips clearly display their "Magnitude" (i.e., the AoE damage generated when they explode). Screenshot below (I use the 48x34 Oanhu map here).

However, when actually deploying in-game, the Magnitude appears to be displayed as {3}, regardless of the actual fuel tank magnitude. Screenshot below (same map, same fuel tank).

Example showing the same effect on map 55x55 Dieron Airfield, with fuel tanks of a different magnitude:

It is possible that this is related to certain Game Options (double-blind or something?), so I have included a save so that they can be inspected. If this is intentional behavior with certain settings then this issue can obviously be closed, but it would be nice to know the cause.
