Hello,
You probably don't have the main menu item for the HP component, so it doesn't have an Itemid associated, so JoomSEF picks the default one - home. Go to Manage Extensions page in JoomSEF, open Hot Property parameters, and on the Common tab, you can either set your "Custom Menu Title" which will be used instead of home, or set "Show Menu Title" to No, so there will be no menu title.
After either change, you need to delete the already created HP URLs using the Manage SEF URLs page (or purge all the URLs) and clear the JoomSEF cache, so they can be recreated with the new configuration.
Best regards,
