Creating NetRestore on 10.10.1 failing

When trying to create a NetRestore image in SIU on 10.10.1 and trying to add custom packages the build will always fail with Error Code 2.

I noticed when you try to Customize Packages that "Essential System Software" reads as 8.03TB but the SSD inside the computer is only 256GB.

I have tried to redownload the "Install OS X Yosemite" from the Mac App Store three times and with all 3 sources the "Essential System Software" will still always read as 8.03TB.

Does anyone else experience this and know how to resolve this?
