Olymp Trade — My trades are closed automatically

I have a strange problem with the Olymp Trade platform. I am sure that something is not adjusted correctly, but I can’t find the solution. I trade forex and have tried trading different pairs, but it’s the same with all the pairs. Whenever I open a trade my trade automatically closes just after a minute or depending on the duration I set. I haven’t placed any TP or SL orders, and can’t understand why it gets closed. Furthermore on the trading terminal on the right side, I can’t even find the TP and SL order, all I have is the amount of my trade and the option to choose a duration.
