Contradiction with Matthew 28:19
Romans 11:13 focuses on Paul's specific ministry to the Gentiles, whereas Matthew 28:19 commands disciples to teach all nations, not specifying any one group.
Matthew 28:19: Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: [teach...: or, make disciples, or, Christians of all nations]
Contradiction with Galatians 2:9
Romans 11:13 highlights Paul's apostleship to the Gentiles, but Galatians 2:9 discusses how James, Cephas, and John agreed that Paul should go to the Gentiles while they go to the circumcised, potentially creating a division of ministry focus.
Galatians 2:9: And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we [should go] unto the heathen, and they unto the circumcision.
Contradiction with Acts 22:21

Acts 22:21: And he said unto me, Depart: for I will send thee far hence unto the Gentiles.

Acts 13:46: Then Paul and Barnabas waxed bold, and said, It was necessary that the word of God should first have been spoken to you: but seeing ye put it from you, and judge yourselves unworthy of everlasting life, lo, we turn to the Gentiles.
Contradiction with Galatians 1:16-17
Romans 11:13 boasts of Paul's ministry to the Gentiles, while Galatians 1:16-17 describes how Paul conferred not with flesh and blood nor went to Jerusalem to receive his commission, highlighting a more divine than self-glorifying aspect of his mission.
Galatians 1:16-17: To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
