Repro Steps:

1) Create a new page
2) Create two new Components (Component_A and Component_B)
3) Inside of Component A, create a Gauge of your choice (I used RadialTicks).
4) Copy the Gauge layer from the Navigator.
5) Open Component_B, and attempt to paste Component_A's Gauge into Component_B.
Observe how no pasting takes place.

Expected Result: Gauges can be copy-pasted like any other component type.
