The two are set to come back after their loan spells at Olympiacos and Nottingham Forest come to an end.
Neither club will take on the option to buy the players.
Miranda managed 11 games for Olympiacos, while Bonatini only played five games for Forest during his loan spell.
It is unclear if Wolves will keep the players in the first team squad for next season.
It seems likely the club will try to find a loan or permanent transfer for them both, as they did not do much to show their quality during those loan spells.
