Highlights not working properly

In my game, I’m trying to highlight all of the player’s companions. The scripts are running perfectly, but the highlight instance doesn’t work for all the models I’m trying to highlight.

Here’s a screenshot of what it looks like in game:

Here’s a screenshot of what the highlight instance inside those characters looks like (which is the same as the other ones that are being highlighted correctly):

There can only be 31 (i think?) highlight instances rendered. Just put all of those characters in the same model and put 1 highlight in that model containing all the characters.
