Summary
The Prop Manipulator device is not functioning correctly in the published version of my UEFN map.
As shown in the attached image, I have created a tic-tac-toe (3 in a row) game. The X and O props should become invisible using the Prop Manipulator, but they remain visible in the published map.
The issue is as follows:
In UEFN (test mode / Play Session inside the editor), the Prop Manipulator works correctly and the props are properly hidden as intended.
However, after publishing the map, the Prop Manipulator stops working and the props that should be hidden remain visible during gameplay.

Steps to Reproduce
Create a simple setup in UEFN (e.g., tic-tac-toe / 3-in-a-row using props).
Apply a Prop Manipulator device to hide specific props (X and O pieces).
Test the map in UEFN Play Session mode → props correctly become invisible.
Publish the island.
Join the published version of the island and start a match.
Expected Result
The Prop Manipulator should correctly hide the assigned props both in UEFN Play Session and in the published version of the island.
Observed Result
In UEFN Play Session mode the device works correctly and props are hidden as expected.
However, in the published version of the island, the Prop Manipulator stops working and the props remain visible.

Additional Notes
The issue only occurs in the published version of the island. Everything works correctly inside UEFN Play Session, which suggests a deployment or publishing-related bug affecting the Prop Manipulator behavior.
