Issue with Subassemblies in VAB

[KakaLoe]

Hello

I have got a big problem. When i enter Subassembly mode in Vehicle Assembly Building and i save something in it i can't go back to vehicle building mode. There is "+" in up-right corner of part window. When i click this part it doesn't appear in VAB. 

Important thing is that - symmetry button is faded black.

Please help

thanks

You mean that the "crossed hammer and wrench" button is greyed out? Screenshots would really help us understand the problem in this case

Also, welcome to the forums.
