World Eaters
Can not use:
1 Icon of Flame
2. Favored One
3. Unburning Might

In the Compendium, World Eaters has a lot of weapons that do not have pictures and descriptions. The main description is most likely taken from the game itself, and not from the mod.

The World Eaters Faction

1. Honor in Blood only applies to units from the Cult of Chaos building. But infantry is also produced in other buildings.
2. Mark of Khorne cannot be imposed, for example, on Chaos Terminators.
3. Icon of Vengeance - it is written that it can be imposed only on units with Mark of Chaos, but in the end it is imposed on units with Mark of Khorn, and there are no units with Mark of Chaos at all.
4. Favored One cannot be imposed on anyone.
5. Unburning Might cannot be imposed on anyone.

Check out all of the above in the game.

May I suggest that you release these fixes that you've already made as a patch, at least until it is made redundant by Severus?

Hey! When I pick the Thousands Sons the game crashed
