Problem when trying to print Some Assemblies for Pick List Report

When trying to select some assemblies I have noticed a few irregularities.
I can select and print all assmblies, any one assembly, or a group of
assemblies as long as assembly 0 is selected. If I try and print a
different group of assemblies, say assemblies 2-5, only the first assembly
selected prints. I am currently on 4.0, has anyone else noticed this
problem and is it fixed in 5.x?
