App deleted but floating share buttons still there

I have had to delete the app for debugging my site but the floating social media links (rss, email, facebook, twitter) on the right side of the home page are still visible.

In Chrome they show as broken links with icon missing.
In Safari and iOs Safari the links are still visible with icons.
in Firefox they don’t appear to be visible at all.

I urgently need to fix something on my site. Please could you advise me on how I can complete remove these elements (and any others from this plugin) so that I can debug before restoring again.

Many thanks !
