You can actually... There are three slots for the numbers. If you type in only two, it automatically compensates for it by displaying them in slot 2 and 3 on the port side and slot 1 and 2 on the starboard side, so they're aligned.
I looked into Jack's description.lua and he's forcing two-digit format by disabling one slot, but on both sides the leftmost is disabled, causing the misalignment. :)
edit: in case somebody will read this in future, I now noticed that the two-digit compensation works only with all three slots enabled. So if you want to have two-digits forced, you have to have them misaligned...
