Stock donation not showing as a Capital Gain Property

I made a stock donation to an organization. In the Charitable Contributions Summary, there is  Part II Non-Cash Contributions Summary.  My donation is being listed as a "Other Property 50% Limit" rather than a "Capital Gain Property".  A very similar donation in 2022 was categorized as a "Capital Gain Property", which I believe is correct. Why in 2023 is it not being shown as a Capital Gain?
