I'm using this plugin (Taxonomy List by Muhammad Rehman) and apparently is not longer on develop or support.
I need to show the main taxonomy (custom from my theme) and the child's taxonomies with the count of elements inside. But after a long trying can't resolve the problem and this is my result:

Florida (0) <<<< Must be 3 not 1, because his children's has 1 each one.
- Jacksonville (1)
- Miami (1)
- Saint Petersburg (1)

This must dynamically for each taxonomy.
