How do I sell my old hexaware shares that are still present in demat but not visible in my brokers terminal under holdings?

Hi, So I just wanted to know I used to own a few shares of hexaware and held them through their delisting and subsequent relisting. Now the shares do appear in my Demat, but aren't visible in my brokers terminal window (same broker from whom I bought the shares initially) Is there something I have to do to get the broker to show these shares again or can I just place a sell order and it will be debited from my Demat automatically? Any help will be greatly appreciated!
