Dropped items disappear

I'm enjoying POE2 on Xbox.
Since recently,
dropped items in the end content appear for a few seconds and then disappear.
Even if I log out and log back in,
the same dropped items continue to disappear when this phenomenon occurs. It's very inconvenient.
Please debug this.
Thank you.

Check your "Toggle Item Visibility" (LT + DPAD RIGHT)
and "Always Highlight" (Options - Interface - Gameplay) options.

If in party play, verify which loot allocation mode is applied (it is free for all by default and set by the party leader).
