Hi community,
My colleague and I suddenly run into this issue. When we select any text elements, including creating a new one, not bounded to any styles or components or variables, the colours won’t show any library files. It only shows 1 colour swatch. See image below. This swatch was created in this file somehow. I cannot even delete or modify it.

The file was working the day before, but suddenly broke.
I found this post, but the answer doesn’t address the issue.
Does anyone know how to solve this please? Thank you so much in advance.
