I think I’ve seen several similar reports recently, including this one (Events in Calendar Sending to Pack). It sounds like a bug in the invitee list for DLE.
I tend to agree with @Stephen_Hornak (and many others who’ve said the same thing) regarding DLE. It seems like the benefits it might have aren’t really worth the headaches it causes, but I was a DL in the pre-DLE days, so my experience is all second-hand.
That said, irrespective of our opinions on the matter, it should at least do what it bills itself as doing correctly.
ETA: @edavignon, since you replied on the other thread, do you know if this issue has been reported to the developers for investigation?
