1Password for Safari Icon vanishes from Browser toolbar and Extensions

I properly installed both 1Password 8 and 1Password for Safari apps. They were both working as expected and I was happy with the changes. Then all of the sudden, the 1Password icon you click in the Safari Toolbar was gone. Going into Safari Preferences~Extensions also showed it was no longer there. There is no way that I’ve found to get it back so I was forced to revert to 1Password 7. Any idea why this has happened and how to restore it?
