Different "Apply variable mode" icon in one file only

Hi everyone,

I’ve noticed that the variable mode button in Figma’s UI is different when I open IBM’s Carbon Design System.

See? It’s a swatch book instead of the hexagon. Why? What am I missing?

Thanks!

Each tab is a separate instance of Figma, which requires reloading the tab to get the updated icons.

Yep, that did it. Thanks for the explanation.
