Looking for help.

You can create a group for the eve ing and then go into the person and re assign them to that lost, you should then be able to unstick from ceremony, it is a bit awkward, I think I googled it in the end, good luck

I was wondering this too as I ended up deleting everyone I put in and started again after I wrote it all down on paper lol

Yer @hitched, please make it easy to change which event each guest is attending, there is no option to do this and its very frustrating when looking at your overall guest count for ceremony and evening
