Monster Lore not always showing

Device: PC
Browser: Chrome
OS: Win10

Steps to reproduce:

1. Open Monster database entry, such as

Nihlathak or

Izual.
2. Notice missing Lore section.
3. Confirm the contribution entry that was approved contained the Lore.

Nihlathak Entry example: monsters/nihlathak-t4322.html

Nihlathak Contribution: contributions/nihlathak-t8595.html?hilit=nihlathak

Izual Entry example: monsters/izual-t4307.html

Izual Contribution: contributions/izual-t8597.html

Anything else to add:

Apologies if this it not a bug, or if there is another process involved and certain sections are just not yet updated.
Other contributions approved at the same time show the Lore was added succesfully, such as on

Korlic,

Talic, and

Madawc for example.

Is it possible to somehow add missing lore by users?

Some monster (for example

Stygian Fury) still don't have it, and I am only able to filter the information for ("More" -> "Lore"), not to add/edit it.
