Icon Set not working

Hi there,

I’ve made an icon set in illustrator and brought them into Figma as SVGs but they dont seem to work.

I made about 129 icons in the same AI file but just on different Artboards. I then named them all and dragged them into Figma. I made them into multiple components and then tried to take an instance in a design I was working on. When i tried to change the instance to other varients of the icon i ran into issues concerning the colour and resize. What am i doing wrong?
