Most of my Identity Safe Logins disappeared

I used to have approx. 66 logins in my Identity Safe.  now I only have 22.   I tried access my safe via the Norton Toolbar in IE and via the mobile Identity Safe app - in both I only see 22.   I d not have a local backup of my Identity Safe.  Does anyone know why this happened and whether or not my lost logins can be recovered by Norton? 

(as a side bar: I tried chatting with norton support but they insisted on remote connecting to my computer despite the fact I told them this wasn't device-specific. None of their security certs mentioned Norton or Symantec so I cut of the chat.)
