the React's select component value does not change on UI (the data fetching from c# api)
09:31 02 Jul 2026

I m working on React / Next.js project using Refine package with in build tools and component, so my functionality where I have a problem that is, I m getting data from c-sharp api into my refine/next.js project's Edit page (where I'm updating users data), there is Select component where classes text value available when I m selecting that component's text (in dropdown list) the value is coming from c-sharp api (swagger api) using 'fetch' method properly but does not displayed on the select component field

ex:-
in select's text value list is = 10th, 11th, 12th

data fetch = previous value come from api (ex: 10th)

now we are selecting = 12th in dropdown list

but nothing happened (value still 10th in field)

I hope you guys understood?
