Some buttons do not show after publishing system library

Hi!
Recently I converted the buttons from our design system library into variants.
I have 3 types: Standard button, Buy button and IconButton
After publishing, from other files I can only see the Buy button The other 2 are not available.
However, If I look for the buttons in the system library document they appear in the library and work fine.
Is this a bug? or how can I fix it? it’s really annoying not being able to use the buttons anymore… Thanks!
