- I can't use the same item with more than one group.
- For example;NCM & UDT, NCM & FSM
- Also it is not possible to create groups with all items included. Some items can't be grouped (IMHO). But it doesn't let me finish without creating groups with all items in it. It says "Please sort all items before submitting your response".
If you fix those then I can complete my sorting. Currently it is not possible to complete unless I am doing something wrong which I don't 
For example,
- NCM & UDT
- NCM & FSM (It should be also possible)
