Building results in entirely borked stylesheets

• I cloned the repo
• I installed NPM in the sass-js folder
• I started npm in the same
• I run the localhost (index file) and tested > all good but no icons
• I run the same in the icons-font > half the bootstrap doesn't work (badges, col-breakpoint...), despite that it loads @import "bootstrap/scss/bootstrap"; just like the sass-js one.

What is the problem? The two examples should load the same Bootstrap, just one with, the other without fonts - or not? If not, how would one include the fonts in the full bootstrap bundle?

I am sorry if this has an obvious answer - however the obvious to me seems that if it loads @import "bootstrap/scss/bootstrap";... it should load the full bootstrap, yet it does not seem to.
