E*Trade sucks

I sold 2 TNA put options strike at 54 . I am deep in the money so I got assigned. I am prepared for it. After assignment, my cost is 54 minuses premium collected, end result is I hold 200 shares with unrealized loss on the account depend on market price. However, E*Trade closed my options at that actual loss, then buy 200$ shares at current price. So they instantly created an actual loss right away which I don’t want yet. I sold same options at Schwab, they got me 200 shares at the strike 54$, which is the way it has been! Can’t believe E*trade just decided to do something different than other brokers and claimed because tna is leveraged. My point is I don’t want the loss now, I want to work it off having a paper loss at the moment.
