I had to goto Kodi Add-on Repo and check updates, this was the only way I could get the update to show, so update the Repo and you should be fine - thats what I've done....

My Add-ons
Add-on repository
Kodi Add-on repository
Update [within options]

Update should show, go back and you should see 'Available Updates' as normal. Hope it helps.....
