Binding to parameter is not updating the parameter

Hey all,

Just a quick overview of what I'm trying to accomplish, what I've done, and then what I see as the issue.  I have a direct SQL query that takes parameterized values.  I've created the two parameters and pass them over fine without issue.  I've created lists of acceptable values for this.  I've opened up model relationship view and bound the list to the created parameters.  Whenever I select a value from the bound list, the parameter doesn't update.  Other visuals (text boxes) update with the selected values, but the parameter and the visuals using the direct query will only use the default value I manually selected.

In BI desktop, I can click "Edit Parameters" and select a different value from the list, but it's pretty unintuitive and I do not believe that's an option for users in the web app.

Does anyone have any ideas?
