Hi brickmaker
JA ACM module is an advanced HTML module, the block types are supported by each template specific because each template has different concept and it will support unique style for a block type of JA ACM module.
If you want to have slideshow from another template, you can consider to copy the folder: root/templates/ja_template/acm/slideshow/
and paste into the same 'acm' folder on your current site.
As the style is not supported in the template you're using so you may need to customize css/js if needed.
Regards
