Why didn't I get my leverage on binance futures after i sold my coins??? PLEASE HELP

So I was in matic and it went up by 62% and i had a 50x leverage. on my PNL/POE% was 2000%, but the value that was displayed was $3500, which is the same amount of money I owuld have made if it was in spot. Once I 'sell/short' the coin, I didn't get my leverage bonus.

Also, when I 'sell/short' my profits, my wallet did not display the 50x profit. It only showed that I have 3k profit, not $3k x $40 profit Did I have to use TP/SL to take leveraged profits?

I got 1x leverage on my matic 50x futures.
