Phantom stop losses automatically introduced by webtrader

 
I use the web trader https://trade.mql5.com/trade and use my MT4 account with Xbtfx. When placing a new order, if I omit the stop loss and leave it as 0, the majority of the time it automatically sets a stop loss that is just a pip or two from the entry price, and causes immediate loss. I have lost count of the number of times I lost money like this. I reported to Xbtfx but they said they verified from the logs that the order was actually submitted with the stop loss. So is the webtrader on the browser introducing the stop loss then? I don't think I would be the only person that noticed this problem.
