Hi Jared,
I just tried Irrigation Trainer #6 and used match (now called Clone Equipment) to clone a Hunter PROS-04-CV head around my plan about 3-4 times.
First, try reinstalling the Workstation installer to make sure you have the latest ribbons where the tool is called Clone Equipment (this is a very recent change and the Trainer is in process of being updated).
Uninstall the Land F/X Workstation Component
New Land F/X Workstation Setup (Skip to step 3)
Then, place 1 Head. Click the Clone equipment tool from the ribbon, click the symbol and place the head 4x.
See it it then verifies.
If that doesn't work, let me know what head you're testing with. Maybe it's related to that and I can try replicating the issue that way.
