CMS Made Simple Forums

I just upgraded to the newest version of CGCalendar (and CGExtensions), and now unique_only does not seem to work anymore on the upcoming list. I have uninstalled and reinstalled the calendar module, and still nothing.

CGCalendar 1.5.2
CGExtensions  1.18.3
CMS Made Simple 1.6.6 "Bonde"

Here is my call to the calendar module:

{cms_module module="CGCalendar" display="upcominglist" unique_only=true limit="10" detailpage="calendar" }

I only have one event set up right now, as the reinstall of the module deleted my other ones, and I get the next 10 instances of the event (it is set to go weekly till july)

Is there anything I am doing wrong? This was working with 1.2.5 (but showing the last date of the repeating event)
