"Description" is placed on line below the others

[CaviaPorcellus]

The column heading "Description" is placed below the others (Date, Project, Hours, Rate, and Amount). See screenshot. Built using the default texlive &c packages in Ubuntu (well, Kubuntu) 24.04.

I get this output, unsure if relevant.
