How can I remove all things from a map

[Vincent318]

Hello, I want to build something in CarlaUE4 and want to make it in a map which is already there, for example Town01_Opt. I want to remove all other actors for this, but this doesn't function because some actors are grey in the World Outliner and I can neither click on them, nor delete them. Does somebody know how I can remove all actors from a map (also the grey)? Thank you for your help!

Hello! _Opt maps are composed by sublevels, you can just delete the sublevels and the actor will dissapear
