Trainer Slide shows wrong messages

[SubzeroEclipse]

Description

Originally brought up on Discord but didn't got any answer, I tested to see if it was a me issue and found it on current upcoming too.

Here's a battle with Bug Catcher Rick, where the messages for first KO and last switch-in show up correctly, but immediately after the one for the red HP shows up. And then at half HP it shows a different message while at red nothing does.

And here's one with Calvin with one mon, where at half HP I get the red HP one, and at red I get the first STAB one.
This is my setup:
