Using Alteryx 2021.1, years in Int32 type now display with a comma: 2,021, 2,020 etc.
There ought to be a simple command to eliminate the comma in report tables, etc.
The only solution I can see is to turn them into strings just before the user sees them, but keep them Int32 up to that point when I'm doing arithmetic operations on them -- this seems clunky!
You can turn off the thousands separator in the user settings (Options>User Settings>Localization)
