Guardians not spawning.

I converted my world to Xbox one beta and my guardian farm isn't working guardians aren't spawning, it's in ocean temple location.
In 1.2.3 it has fixed this problem in previous converted worlds. But the game is still not recognizing the Temple in newly converted worlds after 1.2.3 . What I mean by that is if a player converts a world after 1.2.3 any temples that been generated before conversation won't spawn Guardians. But worlds that was in 1.2.2 been fixed.

It's like the game just doesn't recognize the structures after conversation. And it would be annoying to have an update every time a player converts a world to fix this problem. 😲☹😵😦.
