The bug
Due to the fact that since the world height changes the sea level in the Water World superflat preset is no longer at y=105, but is at y=41 instead, ocean monuments no longer generate underwater.

As @Michael Wobst said, if in 1.16.5 ocean monuments generate underwater as expected, 1.16.5 should be removed from the Affected Versions list and this report should be marked as duplicated by MC-216015 as they're the same report
Can confirm in 21w11a.
Relates to MC-215036.
Can confirm in 21w13a.
Can confirm in 21w14a.
I do not see any difference between MC-216015 and this.
Marking this as relates to MC-206214 as in 1.16.5 in the Water World preset ocean monuments generate underwater just as expected.
