MMM-CalendarExt3 appear with "undefined"
- 
 Hello, 
 I’m trying to configure MMM-CalendarExt3 with MMM-GoogleCalendar.
 I tried a lot of config.js configuration but everytime the module appear I see an “undefined” message.Standard calendar show google events, and MMM-GoogleCalendar show google events too. 
 So the Google configuration part should be ok.npm run config:check tells me it’s ok Could it be an installation problem? 
 I tried “npm run install” and “git submodule update --init --recursive” inside the MMM-CalendarExt3 folder but they didn’t solve.
 Thank you

 @sdetweil after some tries, this afternoon, ext3 started showing. 
 But honestly I didn’t install the clipping flix so I did it now
