I set registered users permissions in order to NOT be able to view everyone's transaction logs.
Now if, as registered user, you open the transation logs from the forum menu, you indeed see only your transactions, and it's working as intended but if you use the Filter and add any usernames, such as the admin's username or any members, you're still able to see their transactions.
So, in order to reproduce the issue, simply have a test account with default permissions and you'll see he'll have the same ability admins have to check every users' transactions.
