A problem with selecting texture in a map

[PrisenShift]

Well, first of all, I'm not a professional at the Source Hammer Editor, so if this request seems dumb to you, don't blame at me.

I have one problem here: when I want to select a texture in decompiled September 2003 mappack (map d1_trainstation_0*) I get selected almost the entire map.

How to fix it?
