Solid Edge Expand All in Design Manager leaves some subassemblies collapsed (shown in blue)

Why does Design Manager not expand all Sub-Assembies with Expand All and displays them as blue in the structure?

Solution

When Expand All command is executed, duplicate instances are not expanded. They are marked in Blue color. These instances however can be expanded manually by clicking the plus sign if needed. Once expanded, blue color is removed. This is done for performance purposes.
