Preserving unique content in instances when updates have been applied to component masters

Hello, I’m having issues preserving unique content instances of components.

For example, we recently updated master input field components, and now all instances linked to such components not only has updated constraints etc, but they have now adopted the placeholder text from the master :frowning:

There are loads of mockups for our form designs that had unique text, which we now have to re-input the unique text for…

I’ve read the article about overrides, and don’t understand why this is happening?

Any advice would be very much appreciated…

What changes have been made to the main component in the library? Did you delete the text layer and add a new one? If so then :
