selecting single walls

[Anonymous]

Good evening everyone!
I have a doubt: I have created four walls and Archicad has "merged" them, tho I can't select one single wall anymore as Archicad selects all of them at the same time, as in the following image

Thanks for the help!

Go to the menu Edit->Grouping->Suspend Groups.
Looks like you have Autogroup turn on.
