bug w/ aluminum calculations

somehow when I set three part limits from aluminum ingots (it can be beams, casings and sheets, so no specific item) - all calculation are gone, all zeros

1 screenshot - before I set part limit for casing

2nd screenshot - after I set part limit

as u can see it works well with two part limits but third one break it to zero
maybe I do smth wrong and js don’t get it

P.S. for example: caterium works fine with 3 part limits, so it’s just aluminum
