The Mass was standardized for centuries, until the Second Vatican Council changed the language of the Mass and allowed modern languages instead of the ancient Latin.
Other changes came along, they didn’t change everything at once. 46 years after the Council ended, there are still changes coming at us.
My suggestion: lower your expectations. If you have a printed Mass guideline, follow it and pray on your own.
Vatican II was the “council of the bishops” which was meant to restore more autonomy to the local bishops. (Vatican I had declared the Pope to be infallible in matters of faith and morals.) Part of that autonomy has lead to non-standardization, and even to experimentation.
Canon law allows you to change churches if you want. don’t hesitate or be afraid to look around and see if there is another parish where you are more comfortable.
