do I have overseen that possibility or isn't it existing?
Marking multiple host entries but not possible to delete them at the same time?
There is a "Delete selected" button (trashcan), it should be at the same spot where you can add a new entry with a "+", below the grid.
In the yellow box, right? Not there. It's there on the "Range" Tab

Found it: was a cicada/rebellion issue. As soon as I switched back to opnsense-dark it's there :D
