There seems to be a new bug in Diablo 4, and this time it involves Chaos Armor. Players have been reporting strange behavior and asking if these items are bugged, and it looks like they might be right. A new thread on the official forums brought the issue up today, and Blizzard was quick to jump in with a response.
Community manager Lyricana confirmed the team is already aware of the problem:

“This issue is known to the team and being looked into, thanks for reporting!” – Lyricana
No details yet on what exactly is wrong or when a fix might happen, but the devs are investigating. Since Chaos Armor plays a big role in loot and build crafting, any bug here could mess with Season 10 plans.
We will keep watching for updates and let you know once Blizzard posts more info.
