How to exit short straddle?

I’m new to option selling.

How to exit short straddle without getting peak margin issue or margin shortfall?

The margin required for individual selling each leg is 90k - 100k as per the data shown in the image.

For a short straddle with 2 sell legs the margin is around 80k which is less than the margin for 1 leg.

Is this margin showed is correct?
If yes, will it cause any margin issue, if only one leg is closed,

I mean the margin collected is around 80k for both legs. But the margin required to sell a leg individually is around 90k - 100k. So, I had this doubt.

Can you guys clear my doubt?
