Can you please show us a screen shot after pressing ALT + T on one of your tracks?
I can't imagine how you would have 1906\\2020 stored as one value in your year tag.
If you mean you have one YEAR tag with 1906 and another with 2020 it would be very hard to detect the difference between the year "Nineteen-oh-six" and the "19 June" and the year "Twenty-Twenty".
