I experienced this and thought I would share the fix for others.
When adding the Recent Faq Widget to my homepage it included my homepage as one of the items. I am unsure if this occurs for everybody or just particular themes/setups.
So here is how to fix it.
Edit the plgin:
1. Open the wordpress-faq-manager/faq-widgets.php
2. Locate the line class recent_FAQ_widget extends WP_Widget {
3. Delete or comment out with //
the line global $post;
4. Update file
You will no longer have the weird age/post showing up as a recent FAQ.
