How do I change how much is being taxed in NYS? When I edit the % of eligible income to NYS it leaves the wages as the full annual income instead of the percentage I gave

I moved halfway through the year. When I try to edit my W-2 allocation by listing ~50% and click complete it still shows the total state wages as 100% of my income instead of the ~50% that were earned while a resident of NY state (the company I work for is not located in NYS).
