1.7.1: bug in changing month period?

If I set the data displayed to be monthly, current month, then I want to switch to previous month:

  1. the interaction is not intuitive: in the picker dialog I can change month, but data is not reloaded upon clicking the new month
  2. If, after picking a new month, I click on the “month” radio button again, I get a “loading data” indicator that never finishes - even though site data is small

Please create a bug report with steps to reproduce.
