My stop loss orders doesn't work

I have placed two stop orders one for the USDJPY where i was short and i placed the stop loss order at 113.67 but when the pair rebounded the order did not worked. the price passed above my stop order without closing my position and still i can not close my position. The same happened and with a take profit order at EURUSD, i have the take profit order at 1.0597 but now the pair is trading higher and my position is stil open.
Do you have any idea what is happening? i have never seen something like that before and i am tradong in that platform for over 5 years now. Thank you in advance.
