iPhone stickers

I have a sticker pack that I am trying to delete to no avail. I don't use this sticker pack and I thought I had deleted it but every time I run an update on my apps, it shows up as needing to be updated. The problem is, I can't find the actual pack anywhere. I've done all the usual stuff of trying to find it in the launchpad, or in the messenger app store itself, even the main app store, etc., etc., but it's nowhere to be found.

I would really appreciate some help in trying to figure out why an app that doesn't seem to exist on any device still lives as a live app on my apps list. And it's not showing up with a cloud symbol either so I know it's not one I've downloaded and deleted and then want to re-download again. It's just there....existing somewhere that I can't find it and therefore can't delete it.

Thoughts?
