Itherian property "chests have Extra Artifacts" strange behaviors

version: 0.23.6

Chests contain duplicate artifacts (same type and properties). It’s only graphical.

The amount of properties on found artifacts can go above (6/6) -> (8/6)

Should this sigil property ignore enchanted trashcan settings?
I have it set to prevent normal artifacts from appearing.

Three resource bonuses on one artifact
Nevermind, that can happen.
