Body armour Unique “ Morior Invictus grand regalia” - 5 sockets But active only 4 even I added 5

I am playing Path of Exile 2 on PS5 and I would like to report a possible bug related to item sockets.

I have a Body Armour that shows 5 sockets on the item. I successfully added the 5th socket, and the item visually displays 5 sockets. However, in gameplay, only 4 sockets are active, and the 5th socket cannot be used to support a skill.

I have tried re-equipping the item, restarting the game, and relogging the character, but the issue remains.

This appears to be a socket activation issue rather than a visual problem, as the socket exists but does not function.

Details:
• Platform: PS5
• Game: Path of Exile 2
• Item type: Body Armour name: Morior Invictus grand regalia

Please fix the issue

Best,
