I’m having a similar issue.

I found the issue behind, I had taken component from different library. It had imported its collection automatically.

How to fix this though? I have developed several Design system for clients projects and based on their needs I tend to use some each DS’s design’s in specific project, but even with detaching the variables from the design, after I copy them to clients project, it shows the variable in “Used variables” collections

Idk but I feel variables are hard coded to design and will stick with it for ever.

I know it was the root cause of this issue, but have you solved it yet? (For those projects had variables already been implanted from different libraries)
