@praveeng-lntinfotech Have you uploaded the latest local changes on production server? If yes, then also ensure those fields are not removed from the Content view manager.
Check all of your latest changes are up to date on production server.
Also if you have updated the strapi version on production, delete the package_lock.json file, node_modules folder, build folder from the production server and then run below commands:
- npm install
- npm run build
- npm run develop
Just to ensure cache is cleared too.
