In order to add to the regular set, the icon has to be 1.5px and come from the "Ultimate regular" set from Streamline. This looks like it came from a different, heavier set and doesn't have a stroke. This is so that it works with the rest of our icon set consistently.

@speterson-cc gotcha, makes sense. Is there a better place to add this, or should it not be added to Gamut at all? Working with this design: https://www.figma.com/design/YEkxyL9gxflceQJ2KQDXgT/%F0%9F%90%AD-2.0-concepts?node-id=1428-23667&t=2DwP9rAx6BmhpzD6-4

is there a reason not to just use an up arrow that already exists in Gamut? you're free to add it locally to your project it just seems strange to me that we would need more than a few variants (and is visually confusing, imo). i also know this is coming from design so you're just the messenger here 😅
