Trial timing messed up when I run entire experiment

Hello, 


When I finished my experiment and tried to run it, I noticed the timing of the trials was all messed up. When I test run the trials or blocks separately, it works perfectly. 


I want to show a geometrical shape and a likert scale. When they answer the likert scale, I want an image of lightning to appear. 


Below a piece of the script for my trials, my blocks, and my experiment:



<expt groep1>


/subjects = (1 of 12)


/blocks = [1=traininggroep1; 2-3=testscale; 4-6=testbinair]


</expt>





<block traininggroep1>


/trials = [1-3=noreplace (CSplus_CB1, CSplus_CB1, CSmin_CB1CB5)]


</block>





<block testbinair>


/trials = [1-3=BINAIRTEST]


</block>



<block testscale>


/trials = [1-3=TEST]


</block>





<likert CSplus_CB1>


/numpoints = 11


/anchors = [1 = "zeker geen bliksem"; 6 = "misschien bliksem"; 11 = "zeker wel bliksem"]


/buttonvalues = [1 = "0"; 2 = "1"; 3 = "2"; 4 = "3"; 5="4"; 6="5"; 7="6"; 8="7"; 9="8"; 10="9"; 11="10"]


/anchorwidth = 8%


/position = (50, 90)


/stimulustimes = [4000=CSplus_CB1]


/responsetime = 4000


/responseinterrupt = trial


/correctmessage=true(bliksem, 2000ms)


/correctresponse=(anyresponse)


/pretrialpause = 2000


</likert>





<likert CSmin_CB1CB5>


/numpoints = 11


/anchors = [1 = "zeker geen bliksem"; 6 = "misschien bliksem"; 11 = "zeker wel bliksem"]


/buttonvalues = [1 = "0"; 2 = "1"; 3 = "2"; 4 = "3"; 5="4"; 6="5"; 7="6"; 8="7"; 9="8"; 10="9"; 11="10"]


/anchorwidth = 8%


/position = (50, 90)


/stimulustimes = [4000=CSmin_CB1CB5]


/responsetime = 4000


/responseinterrupt = trial


/correctmessage=true(clearscreen, 2000ms)


/correctresponse=(anyresponse)


/pretrialpause = 2000


</likert>

I noticed the timing of the trials was all messed up.


Would you please explain what exactly "all messed up" means and elaborate on the difference between running your trials in isolation vs. running them in the context of other elements? What is the behavior you expect vs. the behavior you observe in either context?
