duke3dtc.wad HUD bug

Just loaded duke3dtc.wad with ZDoom and instantly noticed a HUD bug:
it shows 0 bullets while the player starts with 120 ammo. Any fix?

Which Duke 3D TC? There have been several over the years.

The main ammo counter gives me the correct number of shots for the pistol. The total ammo storage amount and capacity (far right on status bar) tells me 0. Could be because the pistol does not use stock Doom bullets but rather a custom ammo type.

If so, the author should have made an ammo type adjustment on the status bar.
Anyway, can anyone fix this, please?
