For a Trane vertical upflow the large baffle should have been replaced with the smaller one, and the metal pan on the right side of the coil should have been removed as well.
It helps with airflow across the coil. It is printed in the install manual as well.
I have come across several vertical Tranes that were left the way yours is and have not noticed any functional issues, yet.
The connections are the same for 410 and 22. It is possible that someone mixed refrigerants.
If people only focused on the important things in life there would be a shortage of fishing poles.
