animation in normal mode and test mode are not same

[Tonmoy_leo]

Hello all, I am using  Animate CC 2020 quite new in it, expecting cooperation from the experts, about an issue I really can't find what's exactly the problem. Let me explain the images above

The green line/object is consists of several (total 9, S1-S9 in the timeline) symbols which are converted graphics need to be started from the start point (in the first picture) and need to be stopped at the point(second picture) following the guideline in the animation.

Now the issue is when I play with timeline bar manually the animation is completely okay but when I go to test mode (Command+enter) only a single small part (S9) appears and shown with animation and other 8 symbols(S1-S8) disappear.

Expecting help from experts so that can finish the first project.
