add_to_cart events being for all the the add_to_cart buttons

I was trying to use this plugin but what problem I am facing is add_to_cart event is being triggered for some add_to_cart buttons but others not . Its working for explore page but not working for homepage items display.

gtm.clicklink event is being triggered in that place on the homepage but working for explore page and specific product pages as well .

I have checked everything with the doc :

What can be the possible solution to this?

Thanks
