Multiplayer UI Set Up

Hello, I’m making a multiplayer character select ui like Super Smash Bros, using new input system.
I added two player and each of them have a multiplayer event system and input system ui module.
On UI opened it will set it to each player’s PlayerRoot and SetSelectedGameObejct, and the selected ui was show in event system.But when press ui navigation button on key board and gamepad , only one of the player will update selected UI.
Dose anyone know how to set this right?
Much appreciation!

It seems that to some reason the multi player event system will set the UI group not in its playerroot to uninteractable so that the first player wont be able to select.

I think it is a bug in multiplayer event system, when at first the canvas group was assigned to it , it works but when UI was dynamic to assign it wont work

Finally figure it out , it’s some of my custom disabled the another UI group when the two comes together.
It works perfectly now
