Plugin overriding theme share buttons even after deleted

Hello,

This plugin replaced my theme’s pinterest share button on all posts, even after the plugin was deactivated and deleted. My site is below:

I see from the previous topics that the typical response is
“the plugin uses the pinterest API key which automatically replaces the pin-it button, so this feature can’t be modified.”

However, this should not be the case after the plugin is deleted. Please advise.
