navigation button not working when set analysis is used to define the URL

[KayPong]

Hi, 

I have no problem to use a navigation button to navigate to a sheet of an app by defining its URL directly at the Website URL for the Navigation Button, but not when I use  set analysis (such as the one below) to define the URL. The navigation just failed to navigate to the sheet when I use set analysis.  when I checked on the URL achieved by the set analysis, it perfectly matches to the URL of the sheet which I want it navigate to. 

Does anyone encounter this problem?

max({<kpi_index = {'1.2.1'}>} url)
