How to get rid of default buildings?

[Navy Chief]

I installed Mile High Simulations MCAS Miramar. Not created for P3DV5, but looks great to me, except for default buildings still showing. Is it just a matter of renaming certain bgl files so they do not load? Thanks in advance. NC

P3Dv5?

If yes I think its the same:

A lot of problems with some of kind old free sceneries for P3Dv4 or FSX.
