Padding overridden on some elements

Hi all,
A number of elements padding are being overridden to 0 when running the build.

They’re getting the following added after the set values -
padding-bottom: 0;
padding-left: 0;
padding-right: 0;
padding-top: 0;

I’ve tested with a base installation and I’m noticing it on wrapper-inner, callout-inner on the basic.html template and the lists on the index.

I’m overriding specifics such as $callout-padding by adding !important but it would be nicer if it worked out of the box.

Attached is a screenshot of the build output.

I am having the exact same problem. Formatting is correct when I run “npm start” but breaks when I try to run a build. It works on my old computer, but for the life of me, I can’t make it work on the new build.
