Upgrading Elements 2025

Can you please explain your question in more detail.  Are you saying that photo captions that were available in Elements 2023 are not present in your catalog when you upgraded to Elements 2025?  If so, you need to convert the catalog.   You can't simply import your photos into a new catalog.  (You should have been given the option to convert your old catalog when you first launched the new program.  You may not have seen it.)
