Button/Img Overlays on top of my imported Animate HTML5 video layer won't display

The animation is on top in html preview. I created an animation in Adobe Animate and imported into Captivate Classic 2019. I then created some image overlays and hotspots on top of the animation all on different layers above the animation layer in the layer panel. Nothing on top of the (exported as HTML5-Canvas) animation will  display in a Captivate HTML 5 preview in browser. Ideas? First time doing an animation import to Captivate. Audio issues as well - track won't play (even though the audio track in Animate was a WAV file at 44.1kHz at 16 bit). Any help would be appreciated!!
