When those question marks pop up, it means that you are calling a quest that is either not created or does not have a name given. So: that tells me that you are calling two quests that you have not made.
So, go through the events which cause these question marks to pop up and, since your 'Fathur' (Father?) quest has ID 4, make sure that the only $game_party.quests lines have ID 4.
Remember, anytime you mention another quest, such as $game_party.quests or $game_party.quests, you will initialize it in the menu, and since they don't exist, they show up with default values, including the default name of ? ? ? ? ? ? . So, make ssure all $game_party.quests lines have ID 4, or else change the ID of the 'Fathur' quest in the database.
