Area portal question on rp_rockford_v2b vmf

Hello, so basically, when I finished compiling rp_rockford_v2b on hammer editor, it looks like this :
I can’t see behind some wall because of a texture called areaportal.
I already tried deleting areaportal but then it just gives me an error like areaportal < to something.
There are no leaks in my map.

Thanks, zokeys.

When I try to launch the map (After I’ve deleted the areaporatal) is “portalnum > numareaportals”

PROBLEM SOLVED : I had an area portal leak.
