Wow, good catch, there's a rare one xD. Not too often that you have identical energy while stationary and moving. This was an intentional feature back when the Tactical HUD was being developed--to avoid excessive numbers when they're identical anyway, it just folds them into a single number, but that was long before the inventory energy display was appended, and apparently the latter will also be removed if the former are folded together.
This went unnoticed because the inventory energy values are intentionally hidden when not in Tactical HUD mode, though this shouldn't be contingent on whether the values are the same, as it is now.
Since identical readouts aren't super common anyway, I'm just going to stop the folding altogether--even matching numbers will both be shown. (This only affects energy, none of the other stats.)
