Pressing tab in game doesn't show summoner names

I can see some of them, but most of them are gone and this started happening about 2-3 weeks ago. How can we fix this shit, its annoying ?

Club tag also seems sporadic now.

Settings - Game(or Interface, I forgot) - Show Summoner Names

That's not a bug; That's overwhelmingly likely due to your settings that you are using.

I have the same issue, summoner names show up above the characters, but they do not show up in the tab menu....this isn't an option I'm aware of, but perhaps I'm wrong. Maybe try repairing the client?
