Issue description
In my UI, I noticed a difference in the number of construction part II in the inventory window on the rt side of the screen, and the pop up UI window I get when selecting an object, in this case conveyor belt under construction. The belt under construction shows a number of 0 available CP2's while the Inventory window on the rt side of the screen shows 8 (?). I have attached a screen-shot of the issue.

Reproduction steps
Find a belt that is under construction and waiting for available parts.
Select it. Compare the number of available parts in the belt menu to the main UI inventory window... mine doesn't match (see attached screenshot...)
