Because no track titles are shown/used in your picture. This is a multi-part composition showing WORK and PART instead. You can’t change those texts in Roon. You can however report false metadata for corretion (so all will benefit from it in the future) in Metadata. If you want to correct it just for yourself, please use an external file tag editor if applicable (you can use the forum search to find recommendations from the community) that supports setting the WORK and PART tags or disable the display of WORK and PART for this album (edit Album at the bottom) so track titles get used instead.
