Pages not appearing correctly

I am a new user in Letora. I am designing a content which has several pages with lot's f button's,text box,etc....

while launching the content the articles which is used in the page is not displaying perfectly. The objects used are gets flickering. It's not showing all the objects at a time. I don't even set any time delay to show. If if clicked the next button all the objects used is not displaying like a single image. It shows all those details are separately. Can you guys advice me to overcome that.
