Scouts missing from Events in Scoutbook

We’ve noticed several events recently that have a few Scouts missing from them. I am confident that these Scouts were on the event previously. They are tenured Scouts, not new Scouts, so it’s not an issue of the event being created prior to crossover. It seems to have been different Scouts each time we ran across it. My SM already fixed the ones that he found, so I don’t have a current example to demonstrate. Has anyone else noticed this issue?
