advanced take profit dosn´t work

hello,

i tried to use the advanced take profit but i had a lot of time the problem that the take profit dosn´t work. 

the price hit the level where the TP was (and were a lot higher so the problem was not because of bid/ask spread), than the Advanced take profit line change color to grey and nothing happend... can somebody help me? did i something wrong? 

Plattform was working and online all the time i sat in front of the screen and i have seen it several times live (i used the browser version from c-trader). the thing is, sometime it works very well but i changed nothing in the settings or anything... very confusing. thank you for you help
