As per my understanding of your use-case, you're having one property let say "noteProp" which you're referring in multiple sections of same flow or in the same UI. If this is the case, it's an expected behaviour. As a property could have only one value which is the latest one or one which you've entered in the first section. Property is a placeholder or a memory block which could hold value. You're trying to refer the same placeholder at multiple places, so it's obvious that it will display same value at all the places.
Also, I want to understand how you've configured all the section. Is it rendered in the same flow or execution of a flow in a case?
Kindly elaborate more on your business requirement as well as design for the better understanding of your use-case.
Apologies if my understanding of your use-case went complete astray.
