Updates to components overrides components

It seems a little inconsistent but why is it that sometimes when updating a component by addions (and not deleting or replacing anything) that the update overrides copy or settings to the components

Specific example:
I created a card component with a simple layout heading, instance swap area and options like scroll and pagination as booleans.
I went on using the card and came across scenarios where I aslo needed a search bar- so I went to add it and gave it a boolean as well.

My issue: Receiving the update in my design file overrode all my card heading’s copy to the default. Why is that if I literally only added a new element?
I can understand having to go and turn off the new search boolean on my existing copies (although I think more could be done to help avoid that it does seem avoidable- I would rather go turn it on in the places where )
