Deleting multiple blocks doesn't work

I use blocks inside nested layouts and wanted to delete multiple blocks at once. I could select them with CTRL + left click but nothing happens when I hit delete in the confirmation popup. The popup just closes and nothing else happens.

I’m using Kirby 3.6.1 with PHP 8.0.2.

Is this a known issue?
