Issue

When you are using workflow designer the following error appears:

"Missing reference at SmartObjectField. Error. Item has already been added. Key in Dictionary: Folio' Key being added: Folio. Stack Location: K2process >>> Stack end."

Due to the error this halts you from deploying the process in this scenario.

Symptoms

It appears that this is tied to a number variable only, when using any other variable type such as string or text this works as expected.
