Can not access the PlayerGui in FE?

I have some scripts and Gui's in the StarterGui and when I check from another script or the DeveloperConsole, they don't seem to be there.

I've tried cloning them into the PlayerGui in a model, and then there is nothing inside the model.

How would I access the contents of PlayerGui from a script in Backpack? Right now I have:

local lscr = script.Parent.Parent.PlayerGui.LocalScript 

But it returns nil. Isn't the backpack client sided as well? And shouldn't DevConsole have access to Client and Server?
