Reg Short Sale with multiple buys intraday

I have initially bought 50 shares of KSCL today @ 435.9 and

sold 65 shares @ 436. ( I abruptly short sold 15 shares which got executed and among 65 shares sold 50 didn’t execute)

Later I again bought 50 shares @ 432.8.

Will these transactions account to defaulter of selling shares?

Will there be any loss? If yes how much is it?

How many did you buy and how many did you sell on that day? The answer to your question lies in the answer to my question
