Additional comments
Thank you for reporting this, however right now we don't have maintainer for Joomla 6 and there is no official official work yet done on Joomla 6. It is basically just a branch to prepare some things for 6.0. That said, the bugs you see are "expected". We will fix this when development officially starts. For now we are closing this.
