Combination of names on passport differs from marriage certificate

My husband bears 3 names. He used the names interchangeable on his passport and marriage certificate. on his Nigeria passport is Udo ikechi obinna. While on our marriage certificate his used his baptismal name which is Udo Benjamin ikechi. We are planning to apply for UK Visa as married couple so we will be presenting our marriage certificate. Will the difference in name post a problem for us or is there any kind of document or action to take to prove that he bears the 3 names.
