As I have said, we must have the real Jesus in order to be saved (see 2 Corinthians 11:3-4).
So, if we have been baptized according to Matthew 28:19, the only requirement for salvation, you don't need to be baptized again in the name of Jesus (while if it will alleviate your doubts, it is expedient); all you need to do is acknowledge that the "name" (singular) of the Father and the Son and the Holy Ghost, is "Jesus Christ", as a comparison of Matthew 28:19 and Acts 2:38 will tell you.
Because then you are baptized in the name of Jesus Christ, even though the titles were spoken over you at baptism.
It is only the name of Jesus Christ of Nazareth that actually saves (Acts 4:10-12).
Therefore, if baptism saves (and I believe that it does, Acts 2:38, Romans 6:1-4, Ezekiel 36:25-27, 1 Peter 3:20-21), then it is baptism in the name that saves (not titles); but if you recognize the name that is referred to by the titles, I believe that you are saved.
For the real Jesus is declared to us in Colossians 2:9 (kjv).
