Clear “In posts” data? (Rerun “in posts” search?)

Hey great plugin, first of all. Thank you.

I use a “duplicate post” plugin where I duplicate the previous post and then edit the contents. Unfortunately the feature where it lists out which posts contain the poll ends up listing the posts where the poll used to be and not only where it currently is.

Is there a way to easily clear off what posts it thinks the hook was used in prior, and make it re-populate what posts contain the poll?

Thanks!
