SharePoint Chart WebPart Hyperlink Field is adding an extension to URL (which returns an error)

Created a chart with two series. In Series 1, i want to add a hyperlink under the Other fields section. Under Hyperlink Field, I selected my field (column) "Inventory". The column "Inventory" is of a Hyperlink type. All values in the "Inventory" field are linked to an Excel Services, browser enabled, Document.

In the Chart, on hover of the Series, the URL is displayed at the bottom of the screen and I can clearly see that it is incorrect so obviously a Not Found Error Message windows displays on click.  Here's an example of what I entered in the "Inventory" column and how the chart displays it.

List "Inventory" (column) = https://mysharepointsite/.....documents/myexcelservicesdocument.htm

Chart = https://mysharepointsite/.....documents/myexcelservicesdocument.htm,%20Inventory%20

I entered another URL (used Google.com), just to make sure it was not the document extension that was throwing this off, and it still didn't work. For that address it returns https://www.google.com,%20Inventory%20

It looks like it adds %20Inventory%20 to the end of each URL.

How to solve?
