Running Events v3.3.8 on DNN v.4.7.  I have an events calendar on a page,,,, trying to display a list of the the upcoming N events on the front page.  I added the module, clicked display list view only and chose settings -  no matter what I do, the module only displays the month view.  Also,,, trying to add include events from the another calendar, there are no modules listed in the Add Other Event Module dropdown after selecting Include Other Site Modules.  I have reinstalled events module, but nothing is working.  What am I missing, or is this a major bug?

List view - month view:
There is some kind of cache issue that concerns page editors only: it makes the module keep the current view until the session is ended, even if the view has been changed in the module settings. Try the following:
Change the view in the module settings, close the browser window and open it again. The page should now display the selected view.

Sub calendar:
Have you checked the "Include Other Site Event Modules" checkbox in the SubCalendars settings? Also, the other Events module to be included must be a different module instance, not the same module mirrored from another page (= added to  the page with the "Add Existing Module" option in the Control Panel.

i created an add-on module that does just this.  you can see a working example here.
