Custom nav area feature bugged?

I cannot place custom nav areas into the levels. They seem to be bugged.

Am i just somehow doing something wrong? There are only 3 options in the nav area so i dont see how im messing anything up here…

It seems I stumbled upon the very same issue. @Coyotekins_YouTB1 did you find a solution?

Using UE v5.7.4 which is currently the latest one
