Difference in scrip names on marketwatch and on your holdings
SPML Infra Limited has started trading in the BE category from 27 April and that is the reason why you seeing the stock name as SPMLINFRA-BE.

When a stock moves to BE category, our holdings file automatically picks up the latest category. But you will have to then check for BE stock price on the marketwatch as well. Check the image below, how you can add stocks from a different category. Eventhough you see the stock across categories, it can only trade in one category at a time. If you see BE on your holdings, you need to add the BE category, if you see BL, you will have to add BL. You can also see how BE category stock price/market depth is active.
Holdings page you are seeing LTP as 68.1 but actual price of this stock is around 95.
The reason why you are seeing a difference in the LTP is because the first tick in SPML Infra was at 9:22 AM and until then Kite was showing you the LTP of the stock when it was in BE category the last time exchange had move this stock to BE (this is a bug and we will look at fixing this soon). (NSE website also shows the same value).
