Why does the Nicene Creed not use the attribute ' consubstantial ' for the Holy Spirit?

Following are some excerpts from the Nicene Creed: > I believe in one Lord Jesus Christ, the Only Begotten Son of God, born of the Father before all ages. God from God, Light from Light, true God from true God, begotten, not made, consubstantial with the Father... > >I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is adored and glorified, who has spoken through the prophets. > >(*Source*: United States Conference of Catholic Bishops) Here, the Creed speaks of God the Son as consubstantial with the Father. But when it comes to describing the Holy Spirit, it does not use the attribute 'consubstantial'. What is the explanation for the same? Inputs are welcome from any denomination that has adopted the Nicene Creed.
