Hi, I`ve same issue.
Some entries are not visible from Kee, especially entries from the HomeBanking section. A few of them are visible, you can search for them from within Kee by name, but some of the entries cannot be found and the only option is to search through KeePass.
I just installed Kee for the first time, and this is also happening to me in regards to the search field. Some login/pass combinations cannot be found at all through search.
I finally discovered what the shown entries have in common: I can only see entries from the “Internet” folder in my KeePass2 database. Entries from all other folders (“Banking”, “News”, root folder etc.) are not shown.
