Playstation 2 (Play!) core - 2nd controller not functional

Description

I have two PS3 bluetooth controllers that are automatically configured by retroarch and they work in other cores. However, with PS2 Play! core only one of the controllers is functional. When starting a game, it flashes the info messages for finding both controllers. I am attaching photos of the controller config within the core (F1) and from retroarch itself. I tested this configuration separately with PCSX2 and both controllers work there.

Expected behavior

Both controllers should work.

Actual behavior

Only one of the controllers work.

Steps to reproduce the bug

1. Start any game with two player support and two controllers .
2. Only one controllers works.

Bisect Results

I am new to retroarch, so this is my first installation. Can't really tell when this problem appeared.

Start by reproducing the issue in the Play! core with two PS3 Bluetooth controllers on Debian 10, using the controller configuration and in-game behavior described in the report. Compare the result with PCSX2; the work is done when both controllers are detected and functional in a two-player game.
