problem with scrolling between steps

Hi, I modeled a moving load with constant speed of 1 m/s the load moves from x=0 to x=20, when I get the calculation results, plaxis shows me the output of final time(when the load reaches to x=20) and I want to see the path of moving load between x=0 and x=20, I can’t see what’s going on between the steps I only see the result of the final time, when I want to scroll between steps it changes the construction phases, not between the steps, what can I do with this problem?

 

For examples in the picture that I’ve attached I want to see what’s going on in step 45, but when press the red buttons it goes to step 0 or step 100

 

Regards
