I created a new world when  1.21 came out. I visited my first trial chamber and looted all the vaults (normal and ominous).

Days after I found another trial chambers when caving. I heard the sounds of the vaults when I was lighting the caves around. Far later, I wanted to loot the vaults and I found that the vaults are not detecting me. They're like as if I looted them... I wanted to fight the trial spawners though but found out that creepers and regular hostile mobs are spawning.

I got a cartographer and go to a new trial chambers. I checked the vaults and found that two are working. I get back to my base to prepare myself and when returning all the vaults were broken but the two I checked before....

Is this a known bug ? 
Does someone have this bug ?

I am frustrated...
