I’ve found a small bug in the new Bricks release. I checked the forum and found only a similar bug related to the icon color, but it was in a different place and is already marked as solved in v2.2 RC.
As you can see in the image below, when adding a font via the Font Manager, the save icon is dark. It works correctly and the hover state is also correct, it’s just dark when it’s supposed to be white.
