Hi,
We installed an addon (Copy Issue Link) which worked ok but after uninstalling the addon, the button (Copy Issue Link: to copy the issue link and description) is still there.
If I install the plugin/addon again, two buttons appear. But in the management console I can only see (and uninstall) only one.
Is there something like a cleanup function in Jira?
==== THE PROBLEM IN DETAIL ====
Here’s the button which shows (even after deleting addon)

But nowhere to find…

And if I install the addon again:

I get two buttons

and if I uninstall the addon again, back to one button

I can't get rid of that button (and that button doesn't work either)
