Errors in jOpensim cpanel

Hello, I have a couple of issues I cannot track down.

First, in cpanel - OS Version, at the top:
Notice: Indirect modification of overloaded property jOpenSim\Component\OpenSim\Administrator\Model\RadminModel::$currentsimulators has no effect in /var/www/html/never/administrator/components/com_opensim/src/Model/SimulatorsModel.php on line 184

Second in Simulators: Notice: Indirect modification of overloaded property jOpenSim\Component\OpenSim\Administrator\Model\SimulatorsModel::$currentsimulators has no effect in /var/www/html/never/administrator/components/com_opensim/src/Model/SimulatorsModel.php on line 184

Not sure if they are related.

Cannot enable Profiles, Groups, etc until the xml is updated???

Running Joomla 4.3 and jOpensim Version: 0.4.0.4 RC2

Thanks!
