A couple years ago or so when they changed St. Therese of Lisieux to St. Therese of the Child Jesus — they changed St. Teresa of Avila to St. Teresa of Jesus.
Don’t know why, but maybe it will go back to the older form with the new lectionary/sacramentary, etc.
Your guess is as good as mine.
It causes confusion and breaks continuity. This is not a good thing.
