To reproduce the bug please do the following.
Now check the cluster, the string present in the combo box will be present in the String control.
I have LabVIEW 2013SP1 and I see this behaviour.
I've seen that before, i think it's the same with most any datatype if you change order? For some reason it keeps the data order when the data type order is changed. Annoying and dangerous.
I have seen this behaviour when I was handling a string control and an Instrument resource name. This is seems to be happening with data types similar to string.
With Numeric it doesn't have any impact. Only with the data types similar to string (DAQ config, Resource, etc.,)
Yes, i was thinking if a numeric in the cluster had any effect on the reordering issue, like if you in your example add a numeric as last element and move it first.
