Hi @Phillip_Librojo1, Thank you for sharing this with us and appreciate you sharing this screenshot.

I noticed that the Black and White colors in the Custom Style appear as squares, which might indicate that those color variables are linked to a design copied from the Figma design file.

If the variables continue to be added when copying and pasting the design, it seems that the tools might not be functioning properly. However, I attempted to reproduce this problem without success. Additionally, I haven’t been able to figure out how to delete these color variables from the library pickers yet.
