You need to re-do that baptism in the name of Jesus Christ per Acts 2:38, not just repeat what Jesus said in Matthew 28:19 and have a nameless baptism. Check it out in the New Testament in the book of Acts. NOBODY was EVER baptized in the titles Father, Son or Holy Ghost. That was a Catholic revision during the Council of Nicea in 325 A.D. Nobody was ever even baptized for 325 years after Jesus’ death, burial and resurrection in the titles, but ONLY in His name!
