Update Advanced Session not working properly ?

Hello, I am having a problem with the update session node of the advanced session plugin.

I would like to add a button in the lobby settings to change the maximum number of players (the session being in progress). I therefore call the update session node by modifying the public connection entry with the new number of players.

The problem is that it influences “get max players” as it should, but it also modifies the “get current players” when there are no players entering or exiting. Why ?
