Onhover animations are not working

[pravin-d]

The onhover interactions are not working. Any Idea how to debug ?
This is the params values
{

This is because the z-index of the tag is -1 and so the hover will not work

The hover mode remain default "grab" even I change it into "repulse". Any idea?
