Home Office

I am having an issue entering in my home office information.  I have 2 offices this past year.  First is the home i rented for 7 months.  The second is for the home I purchased and used for the remaining 5 months.  The issue I am having is for the second home office.  When it asks for the "First day used for business" I enter in the day I moved into my new home 8/1/2023 but it tells me that it has to be on or before 12/31/2022.  How is this?
