You'll have to give us more detail - the defaults in Jira are pretty clear and intuitive (although there's a LOT on screen, it is at least obvious), so if you're losing things, it's probably a dodgy set up. However, you aren't giving us much to work with here. You aren't telling us what you mean by "your page" or what you're expecting. For issues, you can search for them, but you aren't telling us what you've tried. The reason you can't find a FAQ is that it's unlikely that "in front of you, unless you've done some dodgy config" is not really going to be of much help to you.
Step back, tell us what you're doing and what you expect, and where you're lost in https://confluence.atlassian.com/display/JIRA/JIRA+User's+Guide
