Interactive components with conditional formatting changing all instances

I’ve used variables and conditional formatting to make my Stepper component interactive. However, when interacting with one instance, the values in its other instances also get altered. How can I make sure it only affects the amount for the one specific instance I interacted with?

Ideally, the solution should be generic, as its instances will be used across numerous files.
