I have a group registration which on the backed on the records page, I see that 6 people are in the group, but the link to view the group members is not there. as you can see the registrants below have a clickable link but not the one at the top. I also ran an export and the persons members in his group were not there. They were there for other registrations.
This was an old issue, and when using the current package, you shouldn't be experiencing this.... at least not the exact situation described in this initial post. The fix that was made can't fix old records, but keeps it from happening again.
The problem was tied to the frontend User Panel. When users would EDIT a group registration, members would get lost. Like I said though, this was found and fixed a while ago.
