issue of a check mode

hi! i´m a beginner in Animate, and have a strange issue that I can´t solve, and would be very grateful if someone could help 

it´s alright when I see the animation in the "space of work " (video 1), but at the time of reproduce it in the "check mode" (video 2) the characters do wrong excess movements that I didn´t create in the edit mode. how could I solve it?
