Problem with many banner at one site

Hello my name is Mike i have question. I have done many banners in Adobe Animate. But lately i tryed to create some kind of gallery of them but i have notice some issues. When i put generated code from animate to wordpress banners doesnt worka well.
They are visible when they are seperated but when i try to make few of them there is always one.
What do you think is there some variables that they double each other or somethig like that? I need just advice how to find solution in Google.
