First number in E counter is always stuck at 0

When opening the f3 screen, the first number in the E counter should display how many entities are on the player’s view. But in this snapshot, that number is always stuck at 0, even if there are entities in the player’s view.

Note: in recent versions, the first number in the E counter hasn’t been working consistently, especially if there’s a wall in the player’s view. This E counter feature is known as “E-ray” by speedrunners and can be used to find bastions in 1.16.1. But in recent versions, this doesn’t work consistently when the bastion is far or if there is a wall between the player and bastion.
