[Super Adventure Box] Associate of Secrets, World 1 achievement bug

Achievement is stuck at 85%, unable to complete due to "Left before the checkpoint" cave location doesn't pop up on enter or even when the 5 baubles inside are collected.

Tried it in both Infantile and Normal modes (got credit for the other caves on either difficulties). Also got until the end of the zone and awaited the warp timer but still no progress.

Two years later, I have the same problem
