dress sottostanti

Hello everyone, when I need to see a view below to have references to work on the plant I am using, I happen that in the drop-down menu of choice of the views available, do not appear all the real ones present in the project, but only some, I believe the "historical". precise that all new projects I create are originated from an old modified and renamed project, for convenience of settings, families, etc.
Can that be the reason for my problem?

Are you sure there are views? it is not enough to have created the levels, it is also necessary that the views are available

So I should create views connected to existing levels, right?
