This is completely normal. GTA San Andreas itself is scripted the way that they can only see it's original objects. That's why SAMP only recommend people to script under 300 objects. It's no way to fix it unfortunately, unless you're making a map yourself, and it'll have to be made with some mapping program that I am unsure of.

if you go to www.*******.com and search for GTA San Andreas Alien City, then you can maybe ask there

Hope I helped
