Cannot run the Gross Margin Income statement: Comparative Income Statement for historical years

Client is trying to run Gross Margin Income statement: Comparative Income Statement for historical years dates and it is not working. I started my new fiscal year but am still finalizing December of 2021. I want to run a gross margin comparative income statement with the second period being Dec1-31 of 2020 but it won't let me. It says the date has to be from 1/1/21-12/31/22. Error: "Invalid date. The start date must be between xx/xx/xxxx and yy/yy/yyyy"

Gross Margin Income statement (regular or comparative) will only run for the working years dates (only current and previous FY dates).

It is program design.
