Shape Map not populating with selected measure from Field Parameter

Two years later, I am having the same issue, so it is disappointing not to be able to find a solution. To answer your question, in my case and I'm sure in the original poster's case, yes - the parameters are producing different values for each LGA. When putting this data in a table, it displays correctly, however when changing the visual to a shape map, the data displays completely incorrectly, and never shows any variation between geographical boundaries.
