Azmeri Spirit Atlas Notables Don't work at All

Both of the following effects appear to just not be happening at all.

Shining Trail - Possessed Monsters in your Maps have 25% chance to release Spirits on Death

In dozens and dozens of kills I've never seen this happen once.

Merging Worlds - When a Monster in your Maps is possessed by a Sacred Spirit, it is also possessed by another random Spirit

This doesn't even have a % chance, yet it never occurs

The word "Sacred" seems specific though, but it has no underline indicating you can click to find out what it means.

Are only Fox and Hare sacred spirits? If so, something in game should make that known, I never saw anything in game that mentioned what a "Sacred" Spirit is.
