Health and HEV chargers don't animate when empty

I started playing again with the Steam release and could have sworn the Health charger had a little shutter that went down when empty. The HEV also used to close up when empty but that doesn’t happen either.
The other animations appear to work.

Is this a known issue?
I’m on Steam and no mods that would affect that.

Thanks

I have not seen these shutters either and I also remember them from the mod.

I do not know if they were removed or whether this is a bug. I did notice one first aid charger that was already empty with the shutters down.
