Buddy Press Not Logging Activity for Users

I've granted support access to our site.

It seems that the system isn't logging any activity for our members.

That search shows someone with an account set-up but the activity shows "Never Active". Any thoughts on how that could happen? It's causing them to not be searchable under the "Last Active" or "Newest Registered" search filters.

Is it also possible to remove the last active text from the search results boxes?

Thanks!
