Configurations changing on there own?!

Hello,

I am working with a large structural assembly with a lot ofdecking. I have creating the decking with multiple configurationsfor the different lengths using a design table. Everything seemedto be working fine, for a while. But sometimes I will open my topassembly and pieces of the decking in my sub-assemblies will havechanged to different configs! A -80 will change to a -20 configwithin a sub-assembly.

Anybody else out there experience this?

Thanks!SolidworksConfigurations design Tables
